no boot options after kubuntu hard disk install
Posted 24 December 2009 - 12:08 AM
I recently attempted to install Kubuntu on a partition on my laptop using UNetBootin. The laptop had Windows Vista installed. However, upon rebooting after the Kubuntu install, i am faced with the GRUB loader with no option to load either Kubuntu or the pre-existing Vista. The steps i took are as follows:
1. downloaded Kubuntu 9.10 "desktop" 32bit version
2. used UNetBootin in hard disk mode, onto C:\ with the above .iso
3. rebooted when prompted and loaded with the unetbootin option
4. was taken to kubuntu desktop, ran the installer
5. created a new partition and swap-space from some free space.
6. here installer failed - some error regarding /cdrom. I overcame this by unmounting the the cdrom drive using `sudo umount -l -r /cdrom' (plus one other option i cant recall)
7. the installer finished and i rebooted when prompted
8. upon reboot i am faced with the GRUB loader with 3 options : two memory checks and one "vista" option that takes me directly to the samsung recovery options.
I am using a Samsung R60plus. More information (may be) available on request.
Any help or advice is appreciated

I presume somehow a recovery partition. the
got in the middle of the procedure.

You need somehow to get on that machine grub.exe (from grub4dos package):
Copy the three files to the root of the hard disk.
Boot, and in the GRUB screen press "c" to get to Command Line.
type in it:
should autocomplete to
root (hd0,[TAB] should give you either (hd0,0) or (hd0,1)
Press [ENTER] to establish root to (hd0,0)
and continue until you get (hopefully) up to:
If it doesn't find grub.exe, try agauin with root (hd0,1)
you should return to the previous screen, but this time you will have loaded grub4dos instead of GRUB, press again "c" for command line mode.
it should boot to your previous Vista, if it doesn't try after having re-established root on the "other" partition.
Then you need to read a bit the guide:
in order to understand the possiblities you have to install grub4dos (if you wish to do so) as primary bootlader (replacing your current GRUB) or if you want to restore your previous Vista bootmgr, you may want to use MBRFIX:
if the GRUB is loaded by the MBR or bootsect.exe if it is loaded by the bootsector/PBR.
