Looks like I'll be hanging onto my aging Abit KN9 mobo a while longer...lucky this board still works. Until UEFI issues get smoothed out over the next generations of hardware I'll hang tight on new hardware purchases

UEFI On Linux Is Like A Pathogen

Basically it is possible to install grub into mbr (for bios boot) and combine all grub modules into one efi file to put it onto a fat partition for booting via efi. There you add a little grub.cfg with
Code:search -sf /boot/grub/grub.cfg source /boot/grub/grub.cfg

i have got absolutely no idea what you want to say. what i tried was compling ipxe as efi target (the default version worked with the used nic), but when i started it via efi shell it did only show a few features (i mainly missed http and sanboot) and did not detect any nic.

abandoned UEFI
a few days ago I bought a Dell Latitude E6420 (off Dell Outlet) and it came with Win7pro, and I wanted to dual-boot it. For me the win7 boot is used purely as a rescue mode and/or download stuff to a fat32 partition for access by linux.
the initial problems were that the win7 install was done with a UEFI boot partition, and I couldn't shrink windows below 160GB, and I wanted to squash it below 40GB ideally.
so I booted a retail win7-64 disk and deleted all partitions completely and created new ones. Windows created new UEFI boot plus the MSR plus its own partition. All seemed well. Then I installed linux and it finished and openSuse12.1-64 appeared to recognise the GPT table and do all the right things and completed to give me a working desktop. However, on rebooting, I couldn't get Windows to boot, and found that linux didn't boot properly either, and I wasted a few hours fiddling with UEFI.
Eventually I gave up, turned UEFI off in the bios, booted a linux rescue image and wiped the UEFI stuff and GPT partition, and created an old DOS style MBR partition. Windows then installed OK creating partition entries as expected, and I quickly had a dual boot system, which I am using to post this.
I am fairly sure if I had a lot of time and infinite I could have made it work, but since the hard drive is only 320GB I didn't need GPT partitioning, and although I wanted to understand how UEFI worked, ran out of time and patience. A few years ago for a short time I used a Macbook at work and dual-booted OSX with Linux, and used rEfit etc quite successfully.
I am thus fairly concerned that it won't be long before BIOSs will only understand UEFI and GPT, and be so locked down so much that the average person won't have any choice in the OS they run. It will also be very difficult for third party tools for making and reproducing OS images, like Acronis, to function effectively at all. Hopefully ARM-based systems will have caught up sufficiently and not have the same lock down?
