:Fatal: VolumeID read error: sector 0 of /dev/hdb not readable

I got to the configuration part and the bootloader was being installed but it failed

Now I can't even get past the partitioning part...

[devils casper]

i think partitions have been corrupted.... boot up through LiveCD and execute 'fdisk -l' command in terminal/konsole. post output here...

it says:
dsl@box:~$ fdisk -l
Cannot open /dev/hda
Cannot open /dev/hdb

[devils casper]

oooops...... partition are corrupted. Partition recovery is poosible through UBCD but thats also tricky.
check media and mnt folders too. is there any icon(s) of hda or hdb partitions?

What's UBCD

And what do you mean by check media and mnt folders

[devils casper]

UBCD is a bootable CD having a lot of partition recovery tools.

And what do you mean by check media and mnt folders

after booting through LiveCD, check media and mnt folders. in some LiveCDs, like Ubuntu and Knoppix, fdisk command shows output on using 'sudo' ( root preveligies ).

sudo fdisk -l

I'll download UBCD as soon as I can.

and I get his from sudo fdisk -l
Disk /dev/hda: 255 heads, 63 sectors, 7476 cylinders

great ! partitions are not corrupted. lets install GRUB again ...

Boot with any LiveCD and in terminal type this command

sudo grub-install /dev/hda

now reboot.......
