[SOLVED] GRUB is accidentally on my USB drive

[rashad360]

Hey, I'm a linux newb and I am in some trouble.

I installed Ubuntu on a portable usb drive using a live CD. But now my computer NEEDS the USB plugged in in order to access the GRUB on it so I can boot into Windows from my hard drive. If I boot up my computer without the USB drive plugged in my computer gives me the prompt "Rescue grub" with the ability to type stuff in. I tried to use F12 on startup of my computer in order to tell it to boot using my hard drive (where my Windows 7 is installed) but still no luck.

If the USB drive is plugged in at start up, I get a neat little menu giving me a choice of booting into either Ubuntu, Windows 7, or the memory test. And all of that works fine.

Basically, the problem is, I want to boot into Windows without needing that darn USB drive having to be plugged in when I start my computer.

Any help would be much appreciated.

you can insert your Windows installation CD and select "Repair" from the menu (after selecting some options like keyboard and stuff..).
Then enter

bootsect /nt60 C:\

Now your MBR should be repaired. If Grub was really installed on the USB drive, you should be able to boot Linmux still from that once plugged in.

Hi,
The following come from Saikee's Just Booting Tips on the Just Linux forum.

1 Using a Windows installation disc:
Boot up the installation disc
Choose your language
Click "next"
Click "Repair your computer"

OR
2 Using Windows on the HD
Boot into Windows.
If the booting instructions are still available (Use bcdedit /enum to see), then at a command prompt type

bootrec /fixmbr
bootrec /fixboot

Hope this helps.

Many thanks! That did the trick!
