i installed Ubuntu in a different drive and windows was already there in another drive at first Ubuntu worked and windows was not being opened and now i cant open even Ubuntu and windows. can u please help me opening Ubuntu using bios?
Open the bios (Normally your delete key) and set the boot order to begin with your Ubuntu hard drive. When grub loads and offers a few ubuntu options, pick Ubuntu -(Recovery mode). A menu should load up, select update grub and hopefully that should allow you to select windows or Ubuntu at the grub menu rather than having to worry about the bios.
