Does Linux really benefit from UEFI?


I've used many distros under both legacy and uefi, but my current machine is giving me fits trying to install in uefi mode for most distros I've tried so far. This has me thinking that I've never realized any differences in performance, stability, etc when set up under one or the other; just an increase in complexity of install. So I'm wondering whether there's any real benefit from using Linux in uefi mode? Thanks.

UEFI is implemented predominantly for security reasons - nothing to do with performance/stability.

...and of course support for much larger hard drives using GPT partitioning.

BIOS has supported gpt for years. Including booting.

UEFI is the way of the future - unfortunately some manufacturers have totally cocked up their implementation. Some even listened to M$oft and insisted secure boot was a requirement. When it's really an option.
Lots of mis-information out there, but yes, UEFI does benefit everybody.

Despite it being my own LQ blog entry, this contains a short list of the advantages of UEFI:

There have been other hardware systems that also use ways to configure and present hardware to the OS as is the case of UEFI.

If one reads up on uefi and the reasons, I suspect they will see the reasons bios can't support modern hardware and advanced uses. UEFI has many features that could be used and currently are not.

From https://wiki.manjaro.org/index.php?t..._BIOS_v/s_UEFI

Quote:
MBR-based partition table schemes insert the partitioning information for (usually) four "primary" partitions in the master boot record (MBR) (which on a BIOS system is also the container for code that begins the process of booting the system). In a GPT, the first sector of the disk is reserved for a "protective MBR" such that booting a BIOS-based computer from a GPT disk is supported, but the boot loader and O/S must both be GPT-aware. Regardless of the sector size, the GPT header begins on the second logical block of the device.
No issue for UEFI.

Yep, that's how I understand it.

This is the best answer thus far. I used bootitng for years, which tricked the bios, and supported many many partitions in many ways, and worked, it also supported lots of disk space. These are the claims to fame of the UEFI. The name of the company reflected such: TeraByte Unlimited

My opinion:
Yes, the bios had to be put six feet under like all of use, inevitably.
The alternative(s), and I stress the plural, all have some good and not so good advantages, but the adopted alternative headed by the largest tech giant, benefits the PC industry more than anybody. Yes, it does give us end users some benefits, but now computer manufacturers have a lot more control over the hardware if it goes online, where as in the past, hardware was not likely to be affected when the software was online.

Business is business, sell, sell, sell!

Everybody thinks big business is out to make the peasant happy.
Give your head a shake and put yourself in the business man's shoes.
