Can any one help me : two of my PCs have gone into 'grub rescue'. I tried (now I think foolishly) to install ubuntu 9.10 (which has this new grub animal 'grub 2') . And that is buggy. I just dont know how to come out.
Very strange and *S C A R Y *
1. One machine has existing windows. It had ubuntu 8.04 . I deleted the partition so I could install ubuntu 9.10 . Now the machine refuses to recognise usb stick, usb CDROM so I cannt even boot from them. 2. Other laptop : i thought I will not touch the system that is working fine( ubuntu 9.04) So I used USB CDROM and ubuntu 9.10 disc on it to create a usb stick for 9.10. I did boot from USB CD and chose the stick to install and chose not to install grub as I wanted only one OS on the stick and thought grub will be redundant. (While installing it had asked location of grub on HD(0) etc and that was not relevant . I thought). So I happily ended the process disconnected USB CD ROM drive and restarted the laptop and again I got the sacry 'grub rescue >' prompt
I looked up help on the net but , like some previous sufferers , I got no good help. I am sure there is some good help I can use.

Boot from the windows CD using the conventional optical drive and enter recovery console. type "fixboot /mbr". Reboot.
2. Other laptop : i thought I will not touch the system that is working fine( ubuntu 9.04) So I used USB CDROM and ubuntu 9.10 disc on it to create a usb stick for 9.10.

Boot from Ubuntu, enter rescue mode, type grub-install /dev/hda (or sda or XXX depending on your partition layout.)

http://download.berlios.de/supergrub/sgd_cdrom_1.30.iso
Download this. Most useful for recovery and mbr related stuff.
boot from the cd. get to a grub shell by pressing c root (hd0,1) setup (hd0)
where hdx,y is the disk number starting from 0 and y is the partition where your grub stage 1 and 2 are stored, usually the boot directory of the root partition /boot , but sometimes on a separate boot partition.
Actually you can use and grub bootable media. I have a lenny on a pen drive.

Thanks Nadeem, Swapnil and JTDsouza, I could solve the problem using ubuntu cd , grub command as suggested and going to the console using ctrl-alt-F2 I had to install grub which I could as I had net connectivity automatically detected by the ubuntu CD
