HELP!! Major Ubuntu problem error 21 when booting!!!!!!!!!!!
I am REALLY new to linux so please be 'basic' with me...
okay, this is the problem:
I have a windows vista and windows 7 rc1 32bit dual boot on my laptops hard drive, each on a separate partition. I tried to install ubuntu 9.04 on my 500gb portable external hard drive and all went well. It installed fine but it seems to have moved the boot loader or something onto the portable hd because i can only boot if the portable hd is plugged in. If it isn't it says
"something something something" 1.5
All i want to do is get rid of ubuntu and be back to the normal dual boot. Is that possible to do easily?
That would be great if you can tell me how to get rid of it!!!

Thats right. By default, Ubuntu has installed the Grub on the mbr of the drive where Ubuntu resides. You will need to reinstall grub on the internal drive.
Connect the external drive, boot Ubuntu, and type
sudo grub-install /dev/sda Assuming sda is your internal drive. After this you may need to change the menu.lst file.
If you want to get it to boot back to windows and forget ubuntu for now just unplug your external hd and boot a windows disk to repair the mbr. If this is not an option then there are places to download windows boot repair.
I recommend Super Grub for a start then you will be able to repair your boot with windows and then if you want to boot your external drive you can use the Super Grub disk to boot.
btw my bios can boot usb devices i think. I have run ubuntu 9.04 persistently from a thumb drive by setting the boot order in my bios. I put usb key/drive above notebook hard drive and it went to my thumb drive.

That may be part of your problem, try and change the boot order back to your hd booting first if you can before making any changes.
If you are interested there is a way to have windows boot when your external hd is unplugged and then when you plug in your external hd grub will boot all but you have so much going now I will not get into that now.
