I've had a hell of a time with an extremely unpredictable recently built computer. I don't even know where to start with thetory, so I'll try to share some key facts.Running Fc12It is a Gigabyte GA-EP45T-UD3LR. Reviews on NewEgg havee complaints about instability and it's lack of claimed DDR3 support. I had to use setting described by another reviewer to underclock my memory to get it to work. It has since passed memtest many times.I've encountered mutliple occasions of a complete system freeze.
Booting after freeze seems to require a random amount of restarts to get it to come up. Sometimes I have to hit the reset button 30+ times until I can get the log in prompt to come up.Right now, I have one SATA HDD, in IDE compatibility mode in the system. dropped the FC12 Stable dvd in, the very DVD I installed the current system with, to install it again on another partition. I get to the same point every time, where it hangs:"trying to unpack rootfs image as initramfs"Googling that didn't help me much, since it mostly seemed to address people messing with their own kernel builds.
If I choose "boot from local drive" on the options list from the install DVD, it goes to "PRESS ANY KEY TO REBOOT" with a blinking underscore cursor. Where when I boot normally, it will either give me JUST the blinking underscore alone, or the FC loading screen with no progress. I suspect this motherboard is a pile of **** and needs to be RMA'ed, or simply returned. Anyone care to support or reject that hypothesis?
I've been reading various tutorials of the boot process but still am not clear. I don't care about grub stage 1 and 1.5 at the starting point of when the root filesystem is loaded into VFS(Virtualfilesystem), who is loading it, and from that point on. 1) Does grub load the root filesystem(read only) into VFS?2) Does the kernel load the root filesystem(read only) into VFS?3) Does INIT load the root filesystem(read only) into VFS?after this is concluded....Does INIT or the Kernel create the real root filesystem(rw)...right before the pivot.root

But halts with no rootfs defined and says i need to define one. However it wont continue to boot obviously so am unable to do so. My PC does have raid but its switched off in the bios. I know dual booting is one way to go but would prefer initially to have it in the file. I can boot into the demo version and there is an install option there but doesnt offer my boot disk.

View 3 Replies View RelatedVery 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)
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:
Code:
title grub2
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img
i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.
sudo fdisk -l

After installing QtCurve 1.8-41 from software.opensuse (I've been playing around with themes), whenever I try to boot my computer, it gets to stage 1 of loading (the less colorful splash screen), and about halfway through loading that, the screen goes black and a box in the top left corner says: "Could not start kdeinit4. Check your installation". I'm then taken to failsafe, where I login. When I try to run kdeinit4 from the command line, I get this error:

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?
i have just finish compiling a new kernel from source and would like to know how to load it in to grub2 i know grub the older version was easy to setup with the new kernels but i am not really in to grub2 to know how to load a new kernel to it.

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

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
Code:
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
Code:
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.
I' ve tried to do a iso multiboot 1gb pen stick with grub2 bootloader. I 've already readed all is it possible finding on the WWW but there are some problems i don't understand how to solve.

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)

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?
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.

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.

I have two hard disks sda and sdb. I have Windows XP installed on sda2 and Ubuntu 10.04 on sdb5. When I installed Windows XP, Ubuntu stopped booting. I tried to repair grub2 from a Live CD unsuccessfully. Now I have completely messed up my MBR of both HDDs. I just want to configure grub2 to load both OSes in dual boot mode.

Why this will not load.
I have a hypothetical situation in which I installed my operating system using a RAID1 mirror. At some point I decided that this setup was overkill, my machine isn't system critical, I value doubling my storage space more than speedy recovery, I'm doing routine backups, etc...
Short of backing up my system volume and repartitioning, or otherwise starting over, is there a way I can reconfigure my RAID1 array to only expect one disk so that mdadm no longer reports a Degraded state?
