I have a Sony Vaio notebook with Windows 8(UEFI) installed,after trying to install Ubuntu 12.04 LTS(I cancelled the installation and restarted the pc) from a usb sticky,every time i turn on the computer a GNU GRUB bash show up.I can't figure it out how boot Windows again!


How can i boot Windows(or at least the UEFI menu) from the gnu grub bash?

Note:I already tried to hold/press repeatedly(F2,ESC,SHIFT,...) keys but nothing worked.

  • How far were you in the installation when you cancelled? Also, had you selected to "use the entire disk" or to "install side-by-side with windows"? – WreithKassan Apr 11 '14 at 19:50
  • I selected the 'Something else' option,then realized that i had forgotten to split the hard drive while i still in Windows(as i seen on a tutorial). – Foo User 1 Apr 11 '14 at 20:08
  • But you did not actually proceed with altering the drives? – WreithKassan Apr 11 '14 at 20:08
  • No,i clicked the cancel installation option and then Ubuntu loaded,then i clicked to reboot,in order to boot on Windows again – Foo User 1 Apr 11 '14 at 20:09
  • Hm. That is odd. Make sure the installation media is removed, but either way it shouldn't affect this. If you had not selected a drive option, it should not have installed grub yet. Whereas, this looks to be an incomplete installation to me. – WreithKassan Apr 11 '14 at 20:12

As we were speaking in comments, I decided to post this here. The error is saying you need to load the kernel. This is a page I found that details manually loading the kernel, using the grub terminal. (Which, obviously is what you are looking at)

Loading the Kernel

  • Thanks for the help,but i could't manage to solve it. – Foo User 1 Apr 11 '14 at 21:38

It appears to be a problem with the boot loader (currently Grub). Try re-installing Grub from the Ubuntu live CD. I would recommend the utility Boot-Repair.

If you are not going to use Linux anyways (or you would like to have the Ubuntu install CD simply reinstall Grub), you could restore the Windows boot loader from the Windows recovery CD (you kept it around right?). I'm not an expert on Windows so look at this article for help.
