Can't install on windows partition


I have Win XP Prof on a drive that is partitioned and I am trying to install Mandrake 10 to one of the partitions, but when I select the partion from the installer it says that I need a "root mount point" so I follow the instructions and click "mount point" and select "\". Then it says I need an "actual file system (ex2, somthing, somthing) and I am stuck. What should I do?

I don't know the documentation that comes with mandrake, but reading it could be useful for understanding what is going on here...

You are saying, that you have a disk with more than one partition ?

You will need to know, where your WinXP is installed and what the other partitions are used for - so that you do not accidentally overwrite any important things or even the whole Operating-system

WinXP runs on a filesystem you cannot use to run linux - that is, why you will need to format one of your partitions to contain a filesystem linux can work with ( I would suggest ext3 or ext2)
only after that your installer (which is also linux) can mount the partition and linux can actually be installed to this partition
Unless you have really plenty of RAM installed, you will need to create a swap-partition for linux too (about 2 times as big as the amount of RAM you have).

If you want to share files between the operationg systems you will need to create a FAT32 partition.

Futhermore the root mountpoint is / not \ (its just a windows thing).

Just in case backup any really important files. If you make a mistake it will make recovery a little easier.

you need to format the partition space that you want to install Mandrake on with Linux file system formats. when it's asking you that, it wants to know what type of format/partiton you want to create. if you'd post how much drive space you have to work with there, i'd be glad to give you some more exact guidelines as to how to size them. in the mean time, when you get to the point you're at, it would be a good idea to create (at least) the following partitions. /(root), /swap (a must!), & /home. it's usually a good idea to also create a separate /usr directory. for file system types, i just love Reiser. ext2, ext3, are also nice, but (IMHO) Reiser beats them all. you can mix & match file system types, so it's up to you.

as for the actual partitioning, just click on the empty space you wish to use, resize it into smaller partitions for each one you're going to need, choose the file type, format them when done. just make sure you leave your Windows partition untouched & unformatted & you'll be fine.

here's a basic guideling as to what sizes you might want for each partition & why.......

/(root).......... around 1 gig for this. /(root) usually don't grow much after the intial install if it's a stand alone partition. 1 gig would be plenty if that's the scenerio. if you have the room, make it 2 gigs, but i wouldn't go any higher than that 'cause it would just be wasted space. if you don't create a seperate /usr partition, then /usr will reside here, so see below for /usr comments because you'll want a lot more than 1-2 gigs for this.

/swap............depends on the amount of RAM you have. if you have 256megs of RAM or less, then make this around 800-900 megs. if you have 512megs or more, then keep it around 300-500megs. remember, Linux loves memory & handles it differently than Windows.

/home............all of your personal settings & data will be stored on here. /home doesn't need a whole lot of space to begin with, but as you start saving things/files it can grow rather quickly. if you have the room, give /home as much as you can spare if you're gonna be hoarding mp3's & all sorts of downloads. /home will only grow with as much personal stuff as you store there. several gigs should go to this, but i can't give you a "correct" estimate as to how many. as i said, this will fill up only if you store lots of stuff here.

/usr.........this stores all the binary (executable) files, applications, kernels, & system critical stuff. /usr can get quite large, depending on how many things you install over time. 6 gigs would be a decent amount to give it for a full install with enough breathing room to grow. give it more if you have the space.

Thanks! that is exactly what I needed! I just didn't understand that I needed to re-format my existing windows NTFS partition with a linux file system. I didn't remember having to do that when I installed Fedora yarrow on my other machine. (but I must have) As for partitions I only made the "swap" (2 gig) and the "\" root (46gig) . Do I have to have all the other partitions you suggested? And if I do, can I go back and re-partition my existing "root" partion? Thanks for your help!

you have to have only two: the / (root) and the swap - but if you have really plenty of RAM, you could do without a swap

addition: I think that 2 GB of swap is way too much - but it depends on what you will use the system for

You said early that the swap should be "2 times as much RAM you have" and I have 1 gig so...

2 gigs of swap is way too much, agreed. if you have 1 gig of RAM, then keep your /swap to 500megs tops. as for "do you need to create all those partitions?". well...........technically, no. you could "technically" just have a /(root) & /swap & do everything as root, but that's not really something you'd want to do. so, you (at least) need /(root), /swap, & /home. i just like to create a seperate /usr partition to keep things neater & cleaner. some people even make seperate /var partitions, so they can keep logs & such under control. i'd still suggest the /(root), /swap, /home, /usr scenerio, but if you don't want a seperate /usr partition, make sure you give /(root) plenty of room to grow 'cause that's where /usr will reside. the old "swap should be 2 times RAM" method doesn't really apply any more, these days.

i'd also highly recommend setting up your partitions correctly the first time around. while it is possible resize partitions later on, it is a tedious process that often causes more headaches than it's worth. when resizing a partition that has data on it, there's always the risk of complete data loss. plus, boot entries, mount entries, etc. get changed which can also wreck havoc. do it right the first time, no need to do it again later.......

this was a rule of thumb from the days, where RAM was not as cheap and when you had 256 MB then you had a LOT...

...if you really need more than just a / and a swap-partition: I don't want to start a debate here - really! I'm just saying something and one will have to decide for him/herself...

I have only a / partition and swap - because I wanted:
-to keep it simple
-did not want to waste disk-space
-did not know, when I was partitioning - which partition would need to be how big?...
-still don't know that - I may want to install a new Gnome-Desktop an keep my older one - just in case...or KDE - another version...if I had created separate partitions - I'd have been in trouble pretty soon - nothing one cannot work around, but - I wanted it simple...

It would have been a different story, had I set up a real multi-user-machine or a publicly available server...but I only run linux on a desktop-machine - and never regretted how I did it ( I do have current backups - if my drive crashed - it would make no real difference if I'd have had multiple partitions or just one, so I took the easy way...)
