UEFI Windows Boot Manager preventing CD/DVD Booting!

Hi,

My apologies if this has been already solved.

I reinstalled windows 7 today to do a fresh install of all OSs on this machine, unlike before it did it's UEFI thing and now I'm not able to boot fom linux CD/DVD on my external usb optical disk drive like I was able to yesterday.

Regardless of what option I chose in the BIOS boot options or BIOS boot menu on my intel board it ignores the Disks, points to another external HDD with a GRUB that doesn't work, the screen just shows:
GRUB with a blinking cursor.

Would really really apreciate any solution.

Thanks!

seems more a problem related to your bios and your motherboard, not regarding gentoo. for problems with grub read this: http://www.gentoo.org/doc/en/grub-error-guide.xml in your case maybe you've deleted the grub directory in /boot

Hi, thanks for replying, I haven't got a linux installed yet, just trying to get a linux cd to boot. I'm on old time user of gentoo, but this is the first time I've seen 'windows boot manager' in my bios boost menu! And it's not leting any CD boot!

I doubt it's Windows related either. The drive may have just failed. Are you able to read CD's while inside Windows? Also, have you tried resetting the BIOS to fail safe defaults?
