After my lastest update for Ubuntu and Windows XP, I got a Grub error on booting the next day. ls lists the following (without () ):

sd0 sd1, msdos sd2 sd5 sd6 

When I tried to get into one with (sd0,xy)/ it doesn't detect system or unknown file system error.

I tried to boot to a live session with a Knoppix live CD and found out that all data exists. I also tried to recover with TestDisk and it finds all systems. Here is the test disk result:

                          Start        End     Size in sectors
 1 * HPFS - NTFS              0   1  1  7079 254 63  113740137
 2 E extended LBA          7080   0  1 12161 254 63   81642330
 5 L HPFS - NTFS           7080   1  1 10266 254 63   51199092 [Schule]
   X extended             12031  30  1 12161 254 63    2102625
 6 L Linux Swap           12031  31 33 12161 254 63    2102530

I've 1 winxp-home, 1x Ubuntu (ext3+swap) and 1 winxp prof and then I wrote on mbr with TestDisk but I always get the same errors with Grub.

What should I do? I need both XP and Ubuntu. Help me please.

more infos in answers below - sry for thos confusing style but im working on diff live system and browsers and have to reboot always

the boot info script output is also down below

maybe an advanced user can correct my fail posting - after i can solve my issuse i will register here

thanx and pls help me with those weired issues !

as i still cant just comment my own answer or those on top i again has to put it here as a sepperate answer..... (or even edit - maybe an browser failur using the live cds ... cause this posti can edit)

here the bootinfo script output - but the result is the same as with TestDisk ... but it looks worse - cause it also doesnt detect my old ubuntu ... but there wasnt a eares process or overwrite process visibile ending the last working session

[boot loader]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect /NoExecute=OptOut

multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect



the last part shows that i now use the windows boot loader so that i can acces at least one OS but shouldnt i also get acces to my ubuntu partitions with live-linux-cds ? or do i have to boot with grub to get to those files only ??
