My Windows XP partition type thinks it is Linux swap!

Hi!

This seems strange.

try:

sudo umount /dev/sda1

and then do:

sudo mount /dev/sda1 /media/hda1

It should do the trick.

Good luck!

Best regards
Ruben

Hi Ruben,

I have tried the unmount/mount but the only effect was for hda1 to disappear from places list in ubuntu so I rebooted and found it there..

fdisk -l and gparted have come up with same info as before and XP boot failed same way as before!

Would it be wise, is it possible, to simply change the type of the XP partitions?

it should help, but the change must be done in fstab. Take a backup of fstab.

This thread should give you a hand:

Try booting and accessing windows as normal under boot first. If that does not work take a look at the grub settings as well.

Ok, I had a look at my fstab:

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/hda2
UUID=f7ee3fc0-7918-46e2-b5e1-84b659d0f182 / ext3 defaults,errors=remount-ro 0 1
# /dev/hda1
UUID=DC2409DC2409BB12 /media/hda1 ntfs defaults,nls=utf8,umask=007,gid=46 0 1
# /dev/hda3
UUID=1B33-0A00 /media/hda3 vfat defaults,utf8,umask=007,gid=46 0 1
/dev/hdb /media/cdrom0 udf,iso9660 user,noauto 0 0

What should I be doing with it? Note, in the example fdisk -l is showing the correct ID and system info while as mine is showing linux swap! Should I consider something like "cfdi t" to fix them?

Thanks

Windows has to believe it's booting from the first primary partition. Use the grub "map" and "hide" commands. See https://help.ubuntu.com/community/GrubHowto and the link at the bottom of that page.

You can change the ID displayed by fdisk by using the fdisk "t" command.

fdisk can also reorder your partion table (in x'pert mode) but be warned that the /dev/hdaX numbering might change. This should however not be a problem as long as you are using UUID in /etc/fstab and /boot/grub/menu.lst
