Talk:GNU GRUB

message: The chapter Version 2 (GRUB) claims that there are stage 1, stage 1.5, and stage 2 in GRUB2.
However, according to a short list from the GRUB 2 manual that sums up the changes between grub legacy and grub 2, "The image files (see Images) that make up GRUB have been reorganised; Stage 1, Stage 1.5, and Stage 2 are no more". --195.37.142.74 (talk) 13:33, 12 January 2019 (UTC)
thread_title:  GRUB 2 has no stages 

message: GRUB version 1
The MBR on a hard drive is small (512 bytes) and contains enough machine code to can chain boot GRUB stage 1 from another boot sector such as a partition's volume boot record.  Given the small size of a boot sector, Stage 1 can do little more than load the next stage of GRUB by loading a few disk sectors from a fixed location near the start of the disk (within 1024 cylinders).  Bootloaders other than GRUB can be placed in the MBR, such as LILO,boot0,EFI.
Stage 1 can load Stage 2 directly, but it is normally set up to load Stage 1.5. GRUB Stage 1.5 is located in the first 30 kilobytes of hard disk immediately following the MBR and before the first partition. If this space is not available (Unusual partition table, special disk drivers, GPT or LVM disk) the install of Stage 1.5 will fail. The stage 1.5 image contains filesystem specific drivers. This enables stage 1.5 to directly load stage 2 from a known location in the filesystem, for example from /boot/grub. Stage 2 will then load the default configuration file and any other modules needed.

thread_title:  GRUB BOOT made clearer 

message: Is that adequate?  —Preceding unsigned comment added by 87.174.124.55 (talk) 02:53, 31 May 2010 (UTC)
thread_title:  Category "Research project"?? 

message: It would be worth noting that usually stage 2 is located under /boot/grub, and simply named "stage2". 
We know where stage 1 is (MBR), we know stage 1.5 (within the first 63 sectors), but not stage 2.  — Preceding unsigned comment added by Raghu Udiyar (talk • contribs) 09:51, 9 November 2011 (UTC)
thread_title:  GRUB version 1 

message: The external link to the GRUB2 home page appears broken. From what I can see,
the primary GRUB home page now refers to GRUB2. The older version is called
"GRUB Legacy". I propose adjusting the external links, though this may imply
more significant changes to the article as a whole.

thread_title:  GRUB vs. GRUB2 

message: I came here after microkernel article said Grub was a microkernel(???). Send me a note if there is any truth to that. I think they mistook Grub for Hurd which sound alike(?). GRUB is an IBM PC BIOS Interrupt 13 based bootloader, as described by the "bootsector" analogy. From late 1990's on Interrupt 19 service were expected to be supported for boot services. GRUB wiki complain that an EFI compatible Grub can't be created because of Microsoft FAT licensing. However EFI specs do not require FAT to install an OS, but Microsoft does require FAT EFI loader to load Windows/DOS. See http://www.intel.com/content/www/us/en/architecture-and-technology/unified-extensible-firmware-interface/efi-specifications-general-technology.html (from http://msdn.microsoft.com/en-us/library/windows/hardware/gg463075 ).

thread_title:  GRUB kernel type 

message: Newly installed modern grub shows some welcome text and then the prompt "grub>".
So is this picture in the article showing the menu obsolete? Yurivict (talk) 07:12, 15 September 2012 (UTC)
thread_title:  Grub picture is obsolete? 

message: GRUB's config is menu.lst as is written in it's sources. grub.conf is often connected as a symlink to menu.lst, this causes some problems in situations when link breaks whuch may result in either broken grub config or with two config files without obvious specification which one is actually used.  — Preceding unsigned comment added by 84.47.144.106 (talk) 06:38, 31 January 2013 (UTC)
thread_title:  grub1 config location 

message: :Grub version 1 is still fairly prevalent in older -- but still supported -- releases, e.g., Ubuntu 10.04, CentOS 5.
According to this page, Grub2 has been the default for Ubuntu since Karmic (9.10) - 173.180.59.229 (talk) 01:16, 4 March 2013 (UTC)

message: I'm proposing that Boot Repair Disk be merged into this article. I don't think it warrants its own article, although it seems sufficiently notable to be mentioned alongside the mention of boot-repair (the package that's the entire purpose of the disk) in the "Other utilities" section of GNU GRUB. —me_and 11:07, 2 April 2013 (UTC)
replies: text: Boot-repair-disk can also repair MsWindows-bootloading problems. It's not focused solely on grub and fits very well to be listed with other boot tools, such as on http://en.wikipedia.org/wiki/List_of_live_CDs . Grub is not a tool by design and wouldn't be able to be referenced as a fixable boot-tool. It would be awkward to list this tool from a grub sub-section via list_of_live_cds. I believe it can be mentioned of from the grub wikipage because there's a strong correlation, but the boot-repair-disk can also fix non-grub problems. Swestlake (talk) 06:45, 3 April 2013 (UTC)
replies: text:  Agreed, it wouldn't be that great to merge Boot Repair Disk into the  section. — Dsimic (talk | contribs) 20:11, 18 November 2014 (UTC)

message: There's a lot of info in the section about booting that feels like it should really be linked to the original pages, instead of placed on this page. What do my fellow wikipedians think? 180.66.165.245 (talk) 14:59, 21 July 2018 (UTC)
thread_title:  Bloat in booting section? 

message: Either this article is incorrect, or there should be some clarification whether Grub Legacy is known as both "version zero" and "version one".
"Two major versions of GRUB are in common use: GRUB version 1, called GRUB legacy, ..."
Two sentences later...
Section: "Version 0 (GRUB Legacy)"
...later in the article...
"GRUB version 1 (also known as "GRUB Legacy") is no longer under development and is being phased out"

thread_title:  Version zero vs version one 

message: grub can do a lot more than most people think, it has lots of filesystem drivers and can run on bare metal as a coreboot payload in some cases.
also things like built-in crypto: LUKSv1 and v2(newer key deriv not supported at present), GPG signature verification(to an extent) etc.
For example Debian has this guide: https://cryptsetup-team.pages.debian.net/cryptsetup/encrypted-boot.html
Might be useful as a stub within the article, perhaps referencing the coreboot article. Libreleah (talk) 04:58, 23 June 2023 (UTC)

message: I moved this sentence to talk: "The GNU operating system uses GNU GRUB as its boot loader, as do most Linux distributions and the Solaris operating system on x86 systems, starting with the Solaris 10 1/06 release." 1) GNU is a set of packages, not an operating system. 2) The prior sentence is sufficient. The prior sentence says, "It is predominantly used for Unix-like systems." Timhowardriley (talk) 05:09, 18 July 2023 (UTC)
