I successfully loaded Suse 10 on a SATA HD. The install saw that I had XP on another IDE HD, and I was able to happily use GRUB to boot to either Suse 10 or XP with no problems.

I got a beta version of Windows Vista and installed it on a partition on another IDE HD. After this, I lost GRUB---so, I reinstalled Suse 10 on the SATA HD. I got GRUB back, but I can't boot to either XP or Vista. For the Windows OSes, GRUB gives me two choices: "windows1" and "windows2". When I choose either one of them, I just get this message with blinking cursor: "chainloader (hd0,0)+1" Any suggestions?

Just reinstalling grub (from a rescue-CD) would have been sufficient - since windows overwrites the MBR when you install it...
you could post the output of these commands:
fdisk -l
and also the partition table from the other hd (sdb ? sdc ? - I don't know which it is)
cat /boot/grub/menu.lst
or
cat /boot/grub/grub.conf
(maybe just one of these exist on your system...)

Here are results of fdisk -l:

Hope this helps...Thanks.

nope - it doesn't - its just the half of it...(your grub configuration-file is missing...)
cat /boot/grub/menu.lst
and: what OS is on which disk again?

Here are the results of running the two commands you posted up:

whoomjah@linux:~> su -
Password:
linux:~ # cat/boot/grub/menu.lst
-bash: cat/boot/grub/menu.lst: No such file or directory
linux:~ # cat/boot/grub/grub.conf
-bash: cat/boot/grub/grub.conf: No such file or directory
linux:~ #



Here are the location of the OSes:

/dev/hda1 Windows XP

/dev/hdb1 Windows Vista

/dev/sda2 SUSE 10

/dev/sda1 Swap file for SUSE 10

It is just not possible that there is no grub.conf or menu.lst
You use grub to boot - and it works - therefore there IS a config-file.
Maybe you have a separate /boot partition - which was not mounted when you issued these commands?
There has to be a directory /boot and therein is your kernel as well as another directory
named grub - and in this directory are grub's files and the config-files

I just saw it - might have been a typo on your answer:
cat/boot/grub/grub.conf is wrong (space missing)
cat /boot/grub/grub.conf is working...

Very sorry...I'm new to a lot of command line stuff...I didn't have the space after cat.

Here are the results:

I suggest you do the following (commands - as root):

cp /boot/grub/menu.lst /boot/grub/menu.lst-backup
mind the spaces
This copies the file to menu.lst-backup - that way you will always have the original, which works to boot suse...
then you copy+paste this changed config-file into /boot/grub/menu.lst - so you have this one instead of the old one.
Or you edit in the changed things by hand...use "mc" which is a file-manager with everything built in (F4 lets you edit the file currently selected) or "nano" or "vi" or any other text-editor you like.

It is in a way self-explanatory:
the hide - unhide lines make one windows invisible to the other - because this _could_ cause problems
the "rootnoverivy" lines instruct grub not to try to mount the partition like it does when encountering the "root" statement (present in the entries to boot linux)

Give it a try - the Suse sections are unchanged - so it will still work at least as it was - if not better - which I hope


-edit-
Sorry - I made a typo myself:
rootnoverivy needs to be rootnoverify
changed it...

Thanks, but I am a newbie....

I'm still confused on exactly how to edit the menu.lst file. I log in as root, but get permission denied. I'm not familiar with the other editors...

Please explain again

With which editor are you familiar?
And how (where) do you read this post? I thought you could just copy+paste it, but maybe not...
You run suse - are you just on console or are you using gnome or kde or another graphical desktop?
What do you mean by: ? What and where are you doing to get this message?

Hey...thanks...I figured out how to use kwrite to copy and paste what you wrote...

It worked perfectly!!!!!

Thank you so much!!!

Take care.

nice ...anytime when there is time...
