I was running ubuntu dual boot and wanted to remove windows altogether. Ubuntu was installed on my pc not on disc. I then used os uninstaller to get rid of windows. Ubuntu is still in there somwhere, but after reboot i just get bootmgr missing message. I have no windows disc at hand till monday and only my phone for internet. Any way around this at all? Please help. System is mainly asus, i think. I know there is an ezflash option that appears at reboot... Lost here lol :-) maya
If you don't have any boot CD You will not be able to repair Your MBR :( It is not possible from BIOS setup.
Here is described how to restore Grub from Ubuntu CD:
You can also fix this using other Linux/Unix boot CD's. Even from Windows (installed) or DOS (Grub2Dos).
