Duel boot problem???

Post by Sam111 »

Ok I am trying to help this person. Make his computer duel bootable.

He has create parition for the windows vista os , 2 for the ubuntu os (one for swap the other for the os) , and he has the rest as unallocated space that he wants to format as either ntfs or fat32 for his files.

How he said he did it---> is he did a complete reformat of the harddisk then installed vista.
Then installed ubuntu which installed grub. He can boot fine with both. But when he goes to allocate the unallocated space as either ntfs or fat32. It won't boot.
He gets grub stage 1.5 error 17.

I looked up error 17 and it say's something that it cann't mount something...etc etc
When he allocates the unallocated space he chooses to make it a logical partiton.
Also try choosing extended partition.

I just don't know what it could be even if grub cann't mount the allocated space. It shouldn't effect the bootablity of vista or ubuntu. This was just for files ...etc

Here is the fstab and menu.lst files.
Apparently he has sda instead of hda I think this just means it is SATA instead of IDE or something.

sda1 isn't list I am wondering if that is the problem and how to fix this.
I don't want to have he reinstall everything because it seems to just be a problem when you allocate the unallocate part .

Code: Select all

# menu.lst - See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),
#            grub-md5-crypt, /usr/share/doc/grub
#            and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default		0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).

If you log in with a live cd, and type "sudo fdisk -l" what is the output?

(This may not be the problem, but it is my first instinct)

Assuming that fdisk matches fstab file except for the sda1 entry is not in fstab.
Should their be an entry of that in their.

What else could it be.
Should I tell him to use gpart to allocate the partition and then do a grub-install again.

I am telling to use fat32 but ntfs should be supported in ubuntu by now. Either way this isn't really an issue.

Never had any trouble doing it in XP does but Vista dun no.

Hi,
Long while since i have seen a nix box for a while ,my comments make not make sense , however.....

1) boot using the ubuntu live cd
2) chroot into the linux root partition
3) Install grub from there -- using grubinstall if available
4) you actually make a partiton fat32 by using the mkdosfs command

fdisk may tell us something that has been overlooked. Also, if this is a partition problem then getting EXACT info (info not available in fstab) about said partitions is a good thing.
