Fedora :: Load Grub2 From Grub4dos / Load Directly Grub2 Core Without Passing By Bootstriping Code?

Jan 24, 2011

I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root
What I dont know is how.

In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)

I tried this way:

title grub2
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img

Ubuntu Installation :: GRUB2 Won't Load / What To Do?

May 2, 2010

So I recently tried to install Ubuntu Lucid in the following configuration code...

The installation procedure went fine, and it said it had successfully installed GRUB2. But then, when I tried to boot up the fresh system, GRUB2 didn't even load!!

It's not giving me any GRUB errors, or giving me a 'grub recovery>' prompt, so I suspect that it really isn't even booting into GRUB.

I tried booting into the LiveCD, and installing grub to BOTH /dev/sda and /dev/sdb, but it still does not work, and I am at a loss.

Has anybody else had this problem?

Ubuntu :: Grub2 Won't Load Windows?

May 16, 2011

i installed ubuntu / under /dev/sda1, then installed Win7 under /dev/sda2, as primary. Extended partition and its logicals are for data.

After Win7 installation, i can restore the grub2 for ubuntu, with grub-install and update-grub2. It can even probe the NTFS partition under /dev/sda2. But at restart, when i tried to go to Win7 selection, it does nothing, screen goes black, blank, with a single cursor blinking.
Some data:

Ubuntu Natty 11.04

From /etc/grub/grub.cfg:


menuentry "Windows 7 (loader) (on /dev/sda2)" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(/dev/sda,msdos2)'

General :: Grub2 Failing To Load?

Dec 24, 2010

Very strange Grub2 issue on my Dell Mini 10.

Had Crunchbang Statler on it, and after an update, it would hang at grub, before the grub prompt. ("loading Grub, Welcome to Grub" then blinking cursor, but no prompt or ability to get into rescue)

So I booted into a liveCD, chrooted in, and reinstalled Grub2, purging everything. No dice. Same problem.

So I figured the device maps weren't right, so I pulled off any important files via the live stick, and reinstalled #!. Same problem.

Did a bit of googling, and it seemed like it was most probably not a true Grub2 error, but a bios problem, so I reinstalled XP, flashed to a new bios (A11).

Then reinstalled, this time with Zenwalk (figured it might be a debian thing). Same thing. (note I replaced lilo with Grub2 for puroposes of testing)

Ubuntu Installation :: GRUB2 Fails To Load?

Aug 31, 2010

I am a long time ubuntu user (4.10) and have had a fair bit of experience installing ubuntu and the many mishaps along the way.

So after having no internet for a year I decide to try the new 10.04 flavour by ordering the cd from the site.

Installation went well, no hiccups. But when I restarted the comp it went straight to Xp, so I thought I'll just use the SGD to boot the partion anyway and fix this small problem later.

After SGD confused sda with sdb, I figured out that GRUB2 is now the standard boot loader.

So thats where I am lost, I have searched the forums quickly (25 pages or so..) and realise that I am not going to fix this easily or by trial and error.

here's some info

Ubuntu 10.04 LTS
Intel P4 3.0
1.5 GB RAM

Ubuntu :: Grub2 Boot Floppy To Load From USB?

Sep 20, 2010

I have a number of legacy pcs upon which I would like to install Lubuntu. None have CDROM drives, but they do have floppy drives. None can natively boot from USB devices. My goal is to boot into Grub2 from a floppy with USB support, but I'm having trouble making the floppy. I've seen recommended a few times a command string something like

grub-mkrescue --overlay=/boot/grub --image-type=floppy GRUB2.img
dd if=GRUB2.img of=/dev/fd0

But when I go to do this, grub-mkrescue has no --overlay nor --image-type option. My man grub-mkrescue page only lists --modules and --output as options. I have managed to make a floppy using the commands

grub-mkrescue --output=FILE
dd if=FILE of=/dev/fd0

This disk does boot into Grub2. The problem with this is that I need to add other files to the disk to have USB functionality in Grub2, but this process writes to the floppy in iso9660 format, which mounts as read-only. I have tried to go this route using the mount -o remount option to try to make the fs rewritable, but I also haven't been successful with that (and I think my limited knowledge is restricting me here).

Maybe I can add the correct files to the file output by grub-mkrescue --output before I write it to the floppy, but I also don't know how to do that.

Basically, I'm a little burned out and looking for some direction. Am I going about this wrong? When I try and follow other people's guides, they seem to have options available to them that I don't have. I'm doing all this from my Lubuntu 10.04 live CD, but have found similar things on my regular Ubuntu 10.04 install as well.

Ubuntu Installation :: GRUB2: Error: You Need To Load The Kernel First

Mar 7, 2010

I've been using Ubuntu since 7.10 Gutsy Gibbon. I only recently fully switched to Linux OS's, and Ubuntu is now my primary. I currently have 9.10 installed. CURRENTLY I also have Backtrack 4, and Fedora 12 (Ugh!).Previously, I thought something was wrong with my my filesystem in Ubuntu 9.10, and after an upgrade of the linux kernel, I started to get Error: You need to load the Kernel First. That's where my problems started. I had upgraded to 9.10 from 9.04 and I still had Grub Legacy, so I went through hoops to try and get it to work, but eventually everything just kind of broke, and I completely wiped off my partitions on it and started fresh installs of all 3.

And now that the new linux kernel is released, 2.6.31-20 generic (I think... That's what the highest number on a file I can find in /boot is)I went through a few more hoops and ladders and tried to get it to work, but to no avail. I've looked the internet for a solution to this and tried just about everything but there is no unified answer, and I've seen on Launchpad there are alot of bugs that are classified as 'Fixed', but the problem still remains.I took out the 'quiet splash' part in the GRUB2 line for the newest kernel and it didn't do anything. It only changed it to "Error: Couldn't find file".This is the top two kernels (Main and Recovery for the new, and Main and Recovery for the previous working one)


### BEGIN /etc/grub.d/10_linux ###
menuentry "Ubuntu, Linux 2.6.31-20-generic" {

Ubuntu Installation :: Tricking Old GRUB To Load GRUB2

Jun 8, 2010

So I have an MBR that is Grub legacy,(from HardyHeron) and I cannot edit/upgrade this MBR. (I won't get into the reasons, other than I will mention SafeBoot).

I have a new encrypted LucidLynx Linux installation on partition 4 and an unencrypted /boot partition on partition #3.

When I boot up, I get the "Error 15" Grub error, which is expected as Grub legacy is looking for /boot/grub/stage2 or something like that and /boot/grub/stage2 does not exist in my GRUB2 installation in /boot/grub.

I thought if I could make a link from the GRUB2 binary of interest to /boot/grub/stage2, then maybe the GRUB legacy would be tricked into loading the GRUB2 binary.

what is the binary of interest in the GRUB2 installation that is the main binary?

Software :: GRUB2 Takes A Long Time To Load

Jan 5, 2010

I'm running Ubuntu 9.10 and Windows XP on my system. After installing Ubuntu, it boots normally about once, and then the next time I try to boot, I have to wait a few minutes with it saying "GRUB Loading." I have read other threads about this that say that it is clearly a GRUB2 problem, and something about Windows overwriting something with the MBR; although I haven't booted into windows once in the process of installing Ubuntu (multiple times) or afterward. GRUB version 1.97~beta4.

Ubuntu :: New Triple-booted Installation Doesn't Load Grub2

Aug 5, 2011

I'm attempting to triple boot Windows 7, Mac OS X, and Ubuntu 11.04 on non-Mac hardware. Chameleon is my primary bootloader, which is supposed to chainboot into grub2, but all I get when I choose the Linux boot option is a black screen with blinking cursor. If I try to boot Ubuntu while holding shift, I get the word GRUB, followed by a space and a blinking cursor. grub2 is installed to the Ubuntu partition, and attempts to reinstall it there or to the MBR from a LiveCD result in errors. The MBR and GPT partition tables are synchronized. How do I go about making Ubuntu bootable, without breaking my other two operating systems (or at least leaving them recoverable)?

I built a new desktop computer.The goal was to triple boot the system with Windows 7, Mac OS X Snow Leopard, and Ubuntu 11.04. This endeavor has been significantly more complicated than I originally expected, but with the of a forum-goer at InsanelyMac.com, I've managed to get pretty far with a complex installation process. I've attempted to get Ubuntu running using two methods, neither of them achieving what I'm hoping. Both methods follow.

In the first method, I install Mac OS X using a specially designed install CD that boots into the Snow Leopard installation DVD. The disk is partitioned to have a FAT partition, followed by a Mac OS X journaled partition, ending in a second FAT partition. Mac OS is then installed to the second partition. The Windows boot CD is then used to format the first FAT partition as NTFS, which Windows 7 is then installed to.

As I'm sure you know, this installs Windows Boot Manager. Then I boot into OS X using the boot CD mentioned earlier, and install Chameleon, a bootloader specifically designed for Hackintosh systems, and (supposedly) capable of booting into all three operating systems I'm trying to work with. Finally, I divide and reformat the remaining FAT partition into an ext4 partition and a swap partition, and install Ubuntu to that ext4 partition, with the bootloader installed to the same partition. This will break the Windows bootloader, as now the MBR and GPT tables are no longer syncronized. Ubuntu is also unbootable; attempting to chainload into grub2 leaves me at a black screen with a blinking cursor. The former problem is solved by booting into a LiveCD and installing and running gptsync. Windows is now bootable, but Ubuntu remains in 'limbo'.

The second method I attempted is very similar, but deviates in the last few steps. After installing Windows, I instead install Ubuntu 10.04 LTS, as I thought I might have fewer bootloader issues with that distribution (don't ask why; it was a lucky hunch).This breaks Windows Boot Manager, but this time grub2 throws me into the grub> prompt.I can boot into Ubuntu just fine using the set root/linux/initrd/boot commands, but my motherboard's Ethernet port is not detected by the OS, so I can't directly download and run gptsync. Once I do manage to run it, though, Windows is then also repaired.

Unfortunately, since I can't access the Internet, I can't do a distribution upgrade that way. Trying to upgrade from the recent release's LiveCD...well...doesn't upgrade, just overwrites. So I get the same black screen with blinking cursor problem. I've tried reinstalling grub2 through a LiveCD using grub-install both using the --root-directory flag and the chroot method.

System specifications:
Intel Core i7 (LGA1155)

General :: Grub24Dos Gives Grub2 Capabilities In Grub4dos Package?

Feb 15, 2011

A kind fellow Linux enthusiast told me about DrummerDP project grub24dos.

Here is two links to it.

grub24dos announcement on Reboot
grub24dos on SourceForge

Iam not on that level so I can only trust his words for it. He start up on MsWindows and install it from that OS.

He recommend one do a back up first in case something unexpected happen No warranty.

The very good thing is that it gives grub2 ability to boot isos on a NTFS formatted HDD. Isos that one otherwise had needed to place on a Ext2 formatted partition and that could serve those who want to preserve windows for Gaming?

Ubuntu :: Load Up Gparted With Grub4DOS?

Jul 26, 2010

I built a multi-boot flash drive using the instructions here but unfortunately, those instructions don't include gparted, and I much prefer gparted to the partition managers that are included. How would I go about loading gparted with grub4dos? Either the zip or the iso version is okay with me, I just want to be able to load the live version of the program. I do know that it is included in the ubuntu livecd that I have loaded on the flash drive, but I prefer the standalone version.

Fedora :: Dual Booting - Grub2 To See F15 Or Be Installed Using Grub2?

Jul 11, 2011

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.

Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.
