How to add CB to existing ubuntu uefi system?

http://crunchbang.org – I have a working Ubuntu uefi-install(12.10). My hdd is partioned with gpt and the efi-partition is on "sda1", and I have a bios-grub partition at "sda2". Ubuntu is installed and is booting perfectly in uefi-mode, and obviously has everything in place, like uefi-firmware and bootloader. I then installed Crunchbang the usual way, in legacy-mode, and grub is written to mbr/sda. My bios lets me enable legacy boot support, but still look for uefi first. This way I`m able to boot my system the usual way, by choosing to boot from hdd/mbr in the boot-menu, and then I get the old gr (HowTos)

I'm trying to dual boot Ubuntu 12.04 (or 12.10) with Windows 8 on a new Sony Vaio, but have run into some problems :)

Specifically, my problems seem to come from choosing UEFI or Legacy as the Bootmode in the BIOS.

Here is what I have found so far:

Windows 8 needs to boot using UEFI, and doesn't work in Legacy mode Ubuntu (both 12.04 and 12.10) needs to boot using Legacy, and won't boot (at l

Hello people,

I built a new computer capable of UEFI. Just like I always did, I installed windows 7 64-bit first, hoping that Fedora will pick it and make a line in boot menu.

So I installed windows in UEFI mode. Then put Fedora 17 64-bit and also made sure that I start it in UEFI mode via bios boot shortcut.

CSM in UEFI firmwares do the exact same job as normal BIOS firmware.So it's something specific to the Mac that it's able to boot from a partition's VBR while ignoring the MBR?The reason taht warning is given is because grub-legacy modifies more than just the MBR boot code region.  It can overwrite some parts of GPT header.Not true, the instruction is given in the context of an

Well with a new uefi motherboard comes new nvram, so did you create a new uefi boot manager entry with efibootmgr? Otherwise you could copy your desired bootloader to \EFI\BOOT\BOOTX64.EFIedit: the path above is what the standard indicates is the default uefi application. So it is used when you use external media to boot from for example, in which case you would not have a boot manager entry.

All boot disks seem to be traditionally legacy. UEFI is fairly recent. Setting my laptop to legacy boot only, will boot Parted Magic from USB key but not my OS. Setting dual boot order to legacy first then UEFI, does not have the desired effect. A happy medium is to hit F12 then choose boot device from list.

Which instructions? I don't see how you can have "followed exactly the steps" as described on overclockers *and* all the ways described in the wiki.If you installed grub2 as described in the wiki while in BIOS mode, all you need to do is boot in UEFI mode to complete the installation. I used Ubuntu to do this but anything which will boot UEFI will do.

I got a new DELL XPS 8500 with Windows 8. I understand that it has UEFI (as opposed to traditional boot-loading BIOS system).

I installed Ubuntu 12.04 (not realizing that it doesn't work as well with the secure-load/uefi system). I partitioned my solid state drive so Windows was on one partition, and Ubuntu would be on a new one (sdb7). This always worked with my PREVIOUS computer...

I am building a new PC with a mobo that has UEFI support. This is my first encounter with this, so I have a few questions.

Are there advantages to UEFI as opposed to Legacy booting?If I run a 32 bit XP VM in Virtualbox within Ubuntu 12.04 64 bit, must I use Legacy boot?Is it difficult to convert to UEFI from Legacy if I have started with Legacy and my situation changes? Thanks for your help.

I just got a new system and have been trying to get it set up w/ Win7 & Kubuntu dual-boot, but I've got a major problem. The BIOS of my motherboard (an Asus Crosshair 990FX) is strictly UEFI -- there is no legacy support mode available.
