Now I booted with the LiveCD and ran the script sudo bash boot_info_....
(I mounted disk /dev/sda1 by hand to /home/ubuntu/data, wich is also possible with /dev/sdb1)
Hope this helps.
============================= Boot Info Summary: ==============================
=> Grub0.97 is installed in the MBR of /dev/sda and looks on the same drive
in partition #1 for /boot/grub/stage2 and /boot/grub/menu.lst.
=> No boot loader is installed in the MBR of /dev/sdb

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=7ddcef53-dd34-4e40-96dd-33f02637d3e5 ro

## should update-grub create alternative automagic boot options
## e.g. alternative=true

## should update-grub lock alternative automagic boot options

## additional options to use with the default boot option, but not with the

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=
## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0
## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single
## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all
## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true
## should update-grub adjust the value of the default booted system
## can be true or false
