Having (more) dual boot problems (unbuntu, windows 7)


So, windows 7 has been installed on this computer, but I have need for certain open source software that I can find an equivalent substitute in windows (huh imagine that, someone needing open source programs!) Windows is on hd-. ubuntu on a separate drive, hd1. Everything works fine in GRUB, i can restart my machine multiple times and boot linux... until i go into windows, where it say "We have a problem, Jimmy!", and i'm assuming, thrashes the MBR around because windows is a mean little bully and denies the existence of any other OS in the world. windows will boot that one time, after "fixing" the "problem" but on future restarts, i get nothing booting, just a lonely black screen after the initial start up of "Loading Operating system" and it just sits there.

so, I know this is probably more of a windows problem, but they would deny any need to have a bootloader, let alone another OS, so any ideas on how to fix it?

What version of grub are you using? I believe Grub 2's grub-mkconfig will recognize windows partitions and automatically create a bootup config that includes them. Not sure whether it looks for other hd's though.

If you're using an earlier version of grub, what does your Windows 7 section look like in /boot/grub/menu.lst? Should be something like this, I believe:
Code:
title Windows 7 
root (hd0,0)
savedefault
makeactive
chainloader +1

I believe it is GRUB2 (the one that comes with the latest ubuntu release). It recognizes the partition, and i can load into windows 7 on any restart, the problem comes after that first load into windows, where it runs chkdsk and "repairs" (i believe) the MBR I'll restart now and try to cancel the chk dsk and see if that stops the problem

Which drive is grub on?
Are they sata drives?

Ahh, I think I understand now. I'd had some issues with Windows (updates, I think) causing issues for me until I put grub on my linux partition and made that the bootable one, then let grub chainload the Windows partition.

They are Sata drives, i let the ubuntu installer handle the partitions, so I can't honestly say i know where it put GRUB, but i'm pretty sure it's on the ubuntu install drive (which would be (1,0), i think.

I'm starting to think i might be better off adding one of my old drives to copy files onto and then just redoing everything.

You could go to this site and download and run the bootinfoscript to get more detailed information on your system and all the boot files so you could get more help here:

http://sourceforge.net/projects/bootinfoscript/

There are instructions on using it at a link under Description.

I'm a little surprised that boots at all.
I've not found Win7 itself causes the MBR to be reset, but some Dell utilities do - is this a Dell by any chance ?.

As a test, reboot Win, after the black screen, reboot a Linux liveCD and rerun the bootinfoscript. Let's see what the differences are.

I believe 'super grub disk' and 'plop boot manager' on cd can be used to boot and they will find all operating systems on the machine for loading.

Also once you start linux run command 'sudo update-grub' in terminal and then reboot the computer; it may correct grub installation.

You can also try going to bios boot menu and choosing the second hard disk for booting.

(Note: as syg00 said: backup data before doing system changes)

It is not a dell, it's actually custom built, by myself.

I decided to go ahead and reinstall everything. Windows went in first, then ubunutu. As of right now, windows is in a continuous reload whenever i try to boot into it though. going to run the shell script again, i think i remember seeing a post with a similar issue

Ahh, I think I understand now. I'd had some issues with Windows (updates, I think) causing issues for me until I put grub on my linux partition and made that the bootable one, then let grub chainload the Windows partition.
With sata drives you can have either 1 selected to boot. Meaning you can disconnect the drives to repair boot loaders.On my system I have wins7 & Debian on seperate drives, where as I can select to boot wins 7 drive first or my second drive which has debian (grub2) where I can select either of the OS'es.
If you know what drive has wins 7 then repair it, but if your grub was on that drive then you won't be able to access grub to boot ubuntu.
I myself would then disconnect wins drive & repair grub, reboot select ubuntu drive as first boot device, then update-grub will give access to wins drive.

The initial setup had grub2 on mbr of first hard disk (sda) where windows was installed and windows-mbr on mbr of second hard disk (sdb) which had Linux installed. Although it can be configured this way also, it adds unnecessary complexity. Also there were 3 swaps partitions while only one should be sufficient. It will be interesting to see the bootinfoscript output now.

Ok, i think I have it solved. I removed all but 1 drive, and installed both oses, and a bootloader partition on that drive, and i was able to load into windows and then restart and GRUB2 still came up. Hopefully adding the other drive won't screw things up...

How did you manage a separate bootloader partition?
