View Full Version : Ubuntu won't dual boot with windows 8

October 17th, 2014, 11:17 PM
I can't get ubuntu 14.04 to dual boot with Windows 8. The word thing is, I can boot ubuntu from within windows using system settings, searching for bios and then choose ubuntu to boot from. How can I make my computer load grub from start?

Did you use the wubi installer to install Ubuntu inside windows? Was your windows 8 preinstalled? Does it use UEFI to boot?

Did you install Ubuntu in BIOS boot mode not UEFI boot mode?

May be best to see details, post link to summary report.

I used a usb stick to install, not WUBI. Windows 8 was preinstalled and I'm a bit uncertain i ubuntu tries to use UEFI. In boot repair, the separate boot/efi partition is ticked and set to sda2.
If I boot into windows, choose restart while pressing shift key I will be given the choice to boot into ubuntu. Choosing that, I will get somthing that looks like grub and ubuntu will boot fine but it's really annoying having to go through windows.

I've read a number of posts indicating that with an HP computer uses EFI differently, apparently needs windows files. Not really sure as I don't use UEFI but maybe someone else more familiar can give you details.

It seems hp firmware do not allow you to boot anything other than windows. Hence no ubuntu option in the UEFI. To work around it
1) press esc key while booting to access start up menu 2) press F9 for boot devices menu.

HP 4545s Secure boot off, manually copy files.
HP Manually renamed files to make it work.

Most seem to do the rename of bootx64.efi and make that file really be grub. Then you can set UEFI to boot hard drive.
