Webb Posted June 16, 2015 Share Posted June 16, 2015 I installed Mint 17 on my UEFI/Windows 8.1 box and the bootloader failed to recognize it. I followed the instructions here bcdedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi but that just made it worse. Now it tries to boot from what looks like some sort of network and defaults to Windows after 20-30 seconds when it realizes that there is no bootable network device. I have since deleted the Linux partitions so the boot manager path doesn't exist. How can I restore it to its original state? Quote Link to comment Share on other sites More sharing options...
abarbarian Posted June 16, 2015 Share Posted June 16, 2015 In XP and 7 you could put the original cd in the pc and run a REPAIR from the cd. That sort of thing may be possible from 8.1 or failing that something like, http://lifehacker.com/5984707/five-best-system-rescue-discs Quote Link to comment Share on other sites More sharing options...
Webb Posted June 16, 2015 Author Share Posted June 16, 2015 I could repair it myself if I knew the commands to enter. Google has been a lot of help but messing with the boot manager is dangerous. This computer didn't come with a disk. It has a repair partition but I've never looked into it in detail. Anyway, I was able to get it back to normal behavior by changing some UEFI settings, which appear to override the boot manager. 1 Quote Link to comment Share on other sites More sharing options...
