So I'm having trouble on dual booting a linux software with windows. I have a copy of linux open suse and my computer already came with windows 7 installed so I have that. So I created 5 separate partitions on one drive. One partition for a backup of everything that I have on windows, the I have the original partition C: Drive and three separate partitions for linux which are for root, boot, swap. So I went ahead and installed the Linux opensuse from the cd onto the drive and didnt change anything, left everything to default. Everything looked good restarted machine and started and everything was normal and note (the disk was still inside the laptop). When I took the disk out of the laptop it wouldn't boot not even to windows, it would just say boot manager missing so I'm lost. I don't know why it would do that if I installed it on the hard drive?
