After installing dual boot to my portable hard drive,
I get grub error 21 when booting withought my hard drive connected to my laptop.
and yes, i can boot to vista or backtrack with it connected.
i googled how to fix this error, but it only changed the error to 17 or back to 21, that was it.
currently, im getting error 21.
Also, i can't get my hard drive shown on my computer in vista.
i can see my hard drive in disk management, but when i right click on it,
i only see these two options: delete volume, and help.
