Here is my situation. I shrunk my windows 7 partition to make room for slackware, I then used unetbootin to install slackware 14 32bit on the rest of the hard drive. After that I setup lilo modifying the boot thing (can't remember its name), booting into slackware works perfectly but I have the missing bootMGR error when trying to boot into windows from lilo so I think I messed up my windows settings in lilo.
I believe that to fix this I should use a windows 7 disk to boot from and then repair the bootmgr with it, and then when I'm in windows I can use some kind of boot manager to setup up dual booting. However, I'm at uni and I have no discs to burn and only one 32gb usb stick. Ideally I would like to setup my usb stick to have slackware 14 image and windows 7 image on it, is this possible and how would I go about it? I think it would be dangerous to remove slackware from the usb and just have windows because if i mess it up I might be locked out of both systems, correct me if I'm wrong though.
Any help is much appreciated
