Got in over my head

I installed Ubuntu 9 yesterday on a PC. Everything worked well until I restarted. Now I cannot access either windows or Ubuntu. I get a msg that reads

GRUB loading
error: no such partition
grub rescue>

I have no idea what command to give.

My computer came with windows pre-installed I do not have a boot disc other than Hiren's boot CD. I can see the harddrive and the part. but really have no clue on how to delete Ubuntu completely and have my old PC back. Any help would be great. TIA

Hi, welcome to LQ!

And what partitioning scheme do you see?

Cheers,
Tink

You may try,

Check weather your machine detects any file system

Code:

root (hd0,1)

If it gives ext3 file system or anything similar to this, then try to load kernel image and initrd.img

Code:

kernel /vmlinuz
initrd /initrd.img

Using Fdisk I see

partition 1 Non-dos 20473MB system Unknown usage 3%
partition 2 non-dos 438830MB system NTFS usage 61%
My HDD is 750GB so I think Ubuntu has it somewhere but can't see it.

I tried entering in those commands at grub rescue> but they read unknown command 'root' ect

When I start my PC the system says this

auto detc...port 3...IDE hard disk
sata port0 dvdram
sata port3 st### SMART capable and status BAD
AHCI Port3 device error.

My system was fine before so I know the HDD is ok. I think the install has pooched my windows. On install, I choose it to run duel boot. I cannot get into the recovery console to reinstall windows. Kinda wish I just stuck to the cd version of ubuntu

Is there anything on that Hiren's CD that can run the command fixmbr?
