Talk:BIOS boot partition
GPT-MBR goes to the all-your-base meme page. This probably isnt what you wanted.
Attribution to Mr. Millan ?
Since it appears that GNU GRUB developer User:Robertmh came up with this concept (and integrated it into GRUB), should he be credited? Or should it at least be clearly stated that this is an invention by the GNU GRUB team, so people know where this concept came from? —Hobart (talk) 07:29, 28 February 2012 (UTC)
Hah!IdontNeedEFI confusion regarding endianness
Much confusion has arisen regarding endianness of the "Hah!IdontNeedEFI" GUID:
Look at the fine history:

Sure you want to report a false positive. 2607:FCD0:100:9:0:0:0:3 (talk) 03:33, 8 August 2012 (UTC)
i accidently looked it up before seeing your discussion:
- $ dd if=/dev/sda bs=512 count=40 | xxd | grep 000580
- 40+0 records in
- 40+0 records out
- 20480 bytes (20 kB) copied, 8.4399e-05 s, 243 MB/s
- 0000580: 4861 6821 4964 6f6e 744e 6565 6445 4649 Hah!IdontNeedEFI

I've gathered the following pieces of information in trying to understand it all:
- The first three fields of a UUID/GUID are a 4-byte value, then 2 2-byte values. All subsequent values are single bytes or byte arrays, so only the first 8 bytes are affected by endianness concerns.
- The typical way to write a UUID/GUID's string form in RFCs / Linux-centric documentation is big endian.
- However Microsoft sources tend to write UUID/GUID string forms little endian.
- The byte order of an on-disk GPT is little endian.
