Report "I installed Ubuntu on a 160 gb external hd and it runs fine but now if I unplug the external drive I can not boot into windows. I get a err message " grub" no such file and a lot of numbers. I need to restore or repair the bootloader for windows . As long as I leave the ext.drive plugged in the bootloader comes up and I can select windows and if I dont select windows Ubuntu will load on a few seconds. I want to make windows the default program and load first if I dont pick Ububnu"
