Linux/Win7 Clashing

Post by Starspy on 4th March 2010, 7:35 pm

Hey

I recently recieved a recomendation from my friend that I should install Linux on my computer. I already had windows 7 and I didnt want to install it to my main HD, so I tried to install it to my external USB 500gig HD. It worked out, I booted from the CD and installed it to the external hard drive. It ran fine on there and I soon exited it so I could go to bed.

I woke up the next day and tryed to get on my laptop, meaning to startup win7 and do some HW. I edited the booting order and made it to startup from my main laptop hard drive. It came up with a message saying "Loading GRUB", "GRUB NOT FOUND". I was confused so I tryed to go back and boot linux. It didnt worked when I tried to boot from my external drive with linux on it. I got the same messages. I then went back and tried to boot from my CD with linux on it. That booted fine and linux came up.

I didnt like that. I went into the BIOS menu on startup and edited the startup order to

1. Laptop Hard Drive
2. USB Hard Drive
3. CD E: Drive

I tried to boot from my laptop hard drive again: same message.
Tried to boot from USB hard drive: same message.

I went and booted from my CD again, and in the CD startup the last message said "Boot from Main HD". I pressed that and it said the "Loading GRUB" again. This time.... success. A list came up with all the OS's that were installed on my computer. I had 10 secconds to select Win7 Startup from the list. And everything worked fine.

My question is this: How do I fix this!!!??? Currently my computer wont load windows 7 unless I boot from the CD with my external hard drive plugged in and loaded.

Please help,
Thanks in advance

your GRUB bootloader on your harddrive is corrupt. you may need to reinstall grub because apparently your system currently has no bootloader, thus you cannot boot into any OS, except by CD. by right windows has a bootloader which you can use to include other OSes with a little hack but I cant remember where i found the tool.
try googling around to see how you can reinstall GRUB.
