Bootable USB stick worked for me :') That was one I did not try -.-Original Text
About four months ago I started a thread in this forum regarding a dual - boot system with Gigabyte Hybrid EFI.
Now I have issues with UEFI again. Let me explain:
My new mainboard is an ASUS Sabertooth Z77. It uses the ASUS UEFI BIOS utilities. Installing and booting windows in UEFI mode is no problem, in the boot menu an option is available which looks like this: UEFI: <Device>. The windows installer created the efi partition, the system reserved partition for windows and the actual windows partition which is fine.
However, when inserting the Linux Mint DVD (I burned it 3 times by now, once in the slowest possible speed with verification, once in the slowest possible speed without verification and once in normal speed with verification), the UEFI does not recognize it as UEFI bootable. There simply is no "UEFI: <DVD - XYZ>" entry in the boot menu with the mint dvd inserted.
With the Win7 DVD inserted the entry is there. Also, booting into the efi shell and displaying all EFI mapings, I see both the EFI partition plus the optical drive when the Win7 DVD is inserted, but not when the Mint DVD is inserted. So no manual booting like that from the EFI shell.
Is there anything I can try to make it work?
Note that i've seen this
thread. My prolem is NOT that my UEFI install does not start (I might come to that problem later
). My problem is, that I can't get a device booted into UEFI mode.
With Windows 7 Inserted it looks like this:Boot menuEFI Shell
With Linux Mint 13 DVD inserted:Boot menuEFI Shelllsing blk3 and fs0
General settings:Current SATA settingsBoot settingsGeneral BIOS information
I really hope someone has an idea Moving ODD from SATA II to SATA III connectorhttp://forums.gentoo.org/viewtopic-t-922652-start-0.html
Did not solve it for me.rEFInd:
rEFInd did not help by now. It does find:
- Microsoft EFI
- BOOTX64.EFI // Which is windows
It did not, however, find my optical drive.
