Serious Data Loss -- Live CD Installer

[Billy Charlton]

So I just attempted installing Dapper Beta 2 on my partner's PC.  Pretty 
normal HP PC with Windows XP.

- Used Dapper Beta 2 - live CD
- GUI Installer
- Tried to resize /dev/hda1 to make room for a fresh install of Dapper
- Clicked "next" after dragging resizer widget on partition.  The 
installer brought up a dialog box "Resizing Partition" which was 
immediately followed by dialog "Resizing Failed".  Now drive shows two 
partitions, both type "unknown", first partition size was original size 
- 1, 2nd partition size 1.

Now machine won't boot Windows XP.  I've tried using fdisk from live cd 
to set partition type to HPFS/NTFS, resetting size to full disk size, 
but still says unbootable.

a) Am I now in the doghouse, having hosed the PC?
b) Is there any way to get XP back?
c) Is there a known bug in the Live CD installer for resizing NTFS, or 
is this something new?

Thanks... happy to provide a lot more info, please let me know what else 
is needed.  Hopefully my loss can help prevent this happening to other 
users?

Cheers
Billy
