After reformatting my Windows partition, Linux is corrupt and won't boot.

My first partition is Windows XP, and then I have a / partition, Linux swap partition, and the /home partition. I formated the Windows partition and reinstalled it, and after I reinstalled the boot loader, I get this error:

Remounting root flesystem in read-write mode:
Activating swap partitions: swapon /dev/sda7: Invalid argument [FAILED]
Checking filesystems
fsk.ext3: Bad magic number in super-block /dev/sda8:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contain an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

While trying to open /dev/sda8
Failed to check filesystem. Do you want to repair the error? (Y/N)
(beware, you can lose date)

Is there any way to fix this without reinstalling Linux? I can still access the two partitions from Windows with ext2fsd, so I'm assuming that the swap partition is corrupt.

As far as I can read from your desription, /dev/hda7 is SWAP, and /dev/hda8 is suposed to hold an EXT2 filesystem.

Not being able to mount the swap partition should not stop your linux from booting (unless you have very little main memory)

Could you post your /etc/fstab here?

Your error messages state that sda7 and sda8 are both bad, not just sda7. If it was just the swap partition, only sda7 would be bad, and I think that you should have been able to boot without a swap partition if the problem was only there.

Is sd8 a logical volume set?

Do you have "parted" on your rescue CD? You could try the partition recovery function. (I'd try it on the swap partition first, since there's nothing there to be lost.)

Caution: I recently used the parted recovery function on one of my disks, and my whole XP partition was trashed. (Note that I probably did something stupid [like using M$ tools, too], and I'm not blaming the developers of parted.)

Thanks a lot for the help! I found the problem. Using rescue, I found that these were the actual partitions:
Sda1: 80,000 Mb, tye NTFS
Sda5: 5,000 Mb, type Ext2
Sda6: 1,592 Mb, type Linux Swap
Sda7: 68, 597 Mb, type Ext2
Sda8: 1,000 Mb, type FAT32

Fstab had sda8 as sda6, sda6 as sda7, and sda 7 as sda8. I just edited the file, and now I'm posting this with Linux.
