This may sound somewhat naive, but is that a bad thing, that they both start at the same place? If so, what do I do about it? And, if not, could someone explain to me how that works?
hda3 and hda5 start at the same location... this is probably uncool, yes.

for the other thing... the values for your hdd are written on a label on the drive - usually. If not, you'll have to go ask the manufacturer. Check the values written on the drive against those listen in bios. However, it looks lke you'll want to repartition your drive...

How do I go about seeing if the partition is the problem? When I try to look at the "Extended" partition in YaST, I can't get any information about it in terms of formating and such. I honestly have no clue where it came from, my only guess is that I somehow created it when I installed either SuSE or FC3. The only option that it gives me is to delete the partition--not resize, not reformat, delete... completely. I don't quite know if this is a good thing, however: since I have two partitions that start at the same place, if I delete one, would I not also delete the other? It certainly seems taht way to me, but maybe not. At the same time, though, it also seems like if this is the "Geom Error" GRUB complains about (which I find highly likely), then deleting the partition would resolve that.

One thing at a time - FIRST: check that the hdd manufacturer and the bios agree about how many sectors et al are on the disk. THEN worry about the partitions.

Try:

http://www.faqs.org/docs/linux_admin/x1139.html

if you want to learn about partitions, like the role played by extended partitions.

GRUB GEOM ERROR---Fedora Core 3

I had MDK 10.1 installed and running fairly well but with some garbage that I didn't know how to deal with. Anyway I decided to install Core and go through a tutorial I had obtained.

My system is a 1.4mhz 568meg Dell Optiplex that had a 10 gig HD. I added an 80 gig several months ago.

I don't have windows on but I wanted to keep the MDK when I loaded the Core.

I went through the auto process for partitioning and assumed that everything was OK. Went to boot up and got the Grub geom error. Tried to reinstall, can't. Tried to get to my MDK- can't figure out how. I don't know what possessed me but I made a boot-loader floppy and used it to get the box started at least. Starts to boot and produces a message along the way that goes something like

"kernal panic. Trying........." and the keyboard starts flashing off and on continuously.

The addition of the 80 gig hd did not seem to affect anything but from what I'm reading it may have. The processor is on a removable unit on the motherboard. I just don't have enough knowledge to know where to go with this.

Help is appreciated!

So you cannot boot at all?
What do you mean you can't reinstall? You can ALWAYS reinstall!

Read through the past messages (this thread) very carefully, you'll find hints and a web page to check out that "grub geometry error" thing. Tackle that first.

The simplest thing may be to reinstall - starting with TDK.

When installing FC - you selected the auto option. I've found that this is not as good as the makers seem to indicate. eg. in my case I have two HDD and anaconda, on auto, stuck ALL of FC in the first (8Gb) drive, egnoring the second (80Gb)! I had to use the custom settings to get boot and swap on the first and root on the second. So you have to watch what anaconda is doing, quite carefully.

Presumably you opted to keep all existing linux partitions?
Do you remember if any new partitions were created for FC - it dosn't seem to do this much, preferring to install into the existing partitions: I've seen this happen. You need new partitions for your FC distro. There's an example of how to do this in the "partitions" tutorial I refer to earlier.

Oh - BTW: I'd better to reply explicitly to this bit...

DO NOT TOUCH THE PROCESSOR. (whew)
If you don't know about what you are doing you can really mess things up moving the CPU around.

Take a look at that 80Gb drive ... there's a load of writing on it (you'll have to take it out to do this).
Some of the writing tells you about how to configure it as a master or a slave ... check you've got it right: that is, you got it as a slave AND you are using it as a slave (or master used as a master). Normally you would put it on the same IDE cable as your existing drive, so it should be a SLAVE.

Some of the writing talks about Gb tracks and clusters and stuff like that. Write this down, along with the type etc of the drive.

With the 80Gb drive installed, reboot. Before you get to where GRUB tries to start, you have to get into the setup menue (usually by hitting <del> - you may have to be pretty fast: one method is to hit delete when you hear the floppy noise, and keep hitting it until you see the startup menue.)

In the startup menue, there will be something which tells you about the drives you have installed. There will be a drive name and manufacturer followed by more stuff about cylinders and sectors and so on. Check what bios says against what you wrote down. If they are different, then there is your problem - you'll have to manually set the manufacturers information in the menue.

This is what happens with most grub geometry error problems - it just means that the physical geometry of the drive does not match the geometry read from BIOS.

Hi, Simon-
Thanks for taking the time to get back to me.

BTW- I wasn't really thinking of pulling the processor but I did find out that I can up grade from a 1.4 to a 2.0 (without any kind of adapter) and up to 2.4 with some kind of socket adapter to reflect a different socket. This would be somewhere around $200 so I'm not gonna jump right in just yet.

I was able to get to a 'rescue mode' by using the boot disk I had made. I then was able to look at the partitions that had been laid out. I discovered that I had (probably by default) selected HDB as the home for the bootloader when everything else is on HDA. I set the 80 gig to be the master and the 10 as the slave.

Although I had hoped to keep the MDK 10.1 intact I ended up blowing it away and installed FC3 where the MDK was. I did however partition HDA into two 40 gig sets of partitions (manually this time) so that i can load the MDK 10.1 on the other end of the disk. I see value in switching back and forth to make comparisons.
I then will try to load the WIN2000 on the 10 gig drive.

I haven't read of this being done before and don't want to mess my FC3 install up if I don't have to. Questions I have are:
Will this scenario be workable?
Will I be able to select any one of the three upon boot?
If so, how is that accomplished?
Can I switch between the two LNX installs w/o shutting down and restarting?
While I can flop around in the console I am a neophyte and ask that you be gentle.
Thanks![


ps.Also thanks for the link on partioning- There is little mention of that aspect in the tutorials.

Hmmm ... that will be fine - that will switch the drive labels, but won't solve the geometry error. However, the reinstall (below) should work... I think I mentioned I favoured sticking boot and swap on the smaller drive as hda and used the entire larger hdb for root. I have a vfat partition between boot and swap on the small drive just in case I ever want dos stuff... However, you have different plans:

Many folk do this - however, dosn't MDK need at least two extra partitions (it can probably share FC3's swap partition)?

Ooooh... unless you have a compelling reason for Win2k, I suggest not to use it. 95 through 2k are basically front-ends for DOS and thus quite unstable. NT through XP use UNIX kernel elements, which is why they are more stable. Nonetheless - Window$ dosn't play well with other OS's - I confine mine to another computer.

That said - if you own the Win2k installation CD's (so you've paid the licence fee anyway) then you may as well go dual boot with window$. The main advantage is you can run WINE with all the *.dll files legally yours to use. Similarily with ntfs for linux and similar utilities for acessing ntfs partitions.

Before you go anywhere, you should have a look at the Fedora Forum ... this has a FAQ just for people starting out which you must read.

Installing windows to a linux native machine is quite common. It seems problematical and not something I've tried. Search this page and the fedora forum for clues or just google the question.

Apparently it can work.
You can use either GRUB or the windows bootloader to load whatever you want.
This is often accomplished by getting GRUB to chainload the windows bootloader - in other words you end up editing the grub.conf file (though you may have used LILO). (info grub)
AFAIK: you have to reboot to switch between distros. A switch would involve unloading all the utilities and then the kernel for one distro and then loading everything from the second. If the kernels were identical then I guess you should be able to do this without a reboot - but then, you'd have identical linux's running slightly different packages. You will probably find that you can use your fav MDK stuff in FC3 without trouble.
The terminal is where linux lives - though you can do everything via GUI type daemons, these rely on some other programmer getting it right for you. Not likely - and they hide stuff from you so you don't really know what's going on when something dosn't work.

Don't worry - the infamouse linux learning curve is an illusion: it's actually harder to learn windows... it's just that you did that gradually over a long time so you didn't notice and don't remember (like learning to walk - do you remember being unable to walk?) With linux you are faced with learning a few years of stuff in a few weeks. This is tough. But you'll get there.

Thanx. I'm starting to look at making some better tutorials to guide newbies through things more clearly. Meanwhile, there is a maze of faqs out there and many more sites. Happy hunting and read read read.

then i thought that maybe it was my copy of nld9, so i got out my old copy of suse9.1 and installed it, and it's doing the same bloody thing.

so i went into the bios (first time going into the bios on a laptop) and was amazed at how poor it was.. i honestly have old 386's with better bios. anyway, for the LIFE of me, i couldn't find a SINGLE way to change the configuration of my hard disk- i didn't see a single reference to LBA in the whole thing.

i could reeeeeaally use some help.

This is pretty much exactly my problem. I go into the BIOS, but I just can't find a way to change the configuration of the hdd. There's nothing that references the hdd, or lba, and I'm stuck. Can anyone help me please?

Edit: Alright, I think I figured out why there is no configuration information for the hard drive in the bios, because it's all completely automatic. I still have the same problem though, I tried installing with Lilo instead, but it gave me an error trying to install some file. I really don't know what to try, maybe a different partition setup? And yes, I did check out the link and try as much of it as I could. Any help?

[QUOTE=Mahamadmustafa]i'm having the same problem as 'jordban'.
Edit: Alright so I figured out the grub geom problem, I went in the bios and disabled the pre-os desktop area thing, and it worked. But not the computer just loads grub, and it prompts me for a command, and I don't know what command to give it. I want it to run Linux, which should be freshly installed. Any ideas?

Sorry if I've been a bit quiet these days, I've been too busy to decipher help requests like I normally do. If you want help, you need to be more specific ...

when something exits with "some error", you need to quote the error itself. It also helps to provide the text of the context of the error (usually a few lines before the error occurred is fine).

When you say "the computer just loads GRUB" - what actually happens? It sounds like you are getting a GRUB command prompt - which means that there must have been an error message and GRUB want's you to fix something.

Please also state what your distribution is and what laptop you are trying to install to. Is this a dual boot or a dedicated linux machine?

Please edit your profile to show location and distribution. At the very least it shows you are making an effort, community wise, and it can help folk to communicate with you more efficiently.
