Dec 17, 2010After a stint of using Ubuntu exclusively, I'm trying to install Windows 7 again. However, when I select boot from CD/DVD in the boot menu, I just get the GRUB menu.

Aug 5, 2011So, I've done a lot of stupid things, but this one ranks pretty high. So I'm looking at files here and there, fooling around and tweaking things if I can, but after a while, I get sick and tired of having to fiddle around because a file's owner is root. So, completely ignoring the fact I could start an x session as root, I perform the following command:
chown -hR MY-USERNAME / I'm thinking to myself, "Oh look at me, I'm so smart" until I turn off my laptop for the night and come back this morning, and ubuntu (10.10, 32 bit) says it could not change ICE authority (or something like that) and a few more error messages. Then, I boot into the recovery console, and again, not even bothering to think anything through properly, I chown everything back to root, then chown my home folder back to me. Anyway, I still get the error message, execpt now I can't alt-c to close the first windows that talks about the ICE authority file.
One of my friends has an ubuntu partition, so I can ask him about certain ownerships, but that could take a while and I don't know where to start.
Ubuntu Installation :: Installing BURG Prevents Windows From Booting?
Apr 19, 2010Ubuntu Lucid 10.04 Beta 2 64-bit
Dual-boot with Windows 7 Professional 64-bit
Compaq CQ50-215NR laptop with 3GB system memory, 1.9GHz Athlon X2 QL-60 dual-core processor, nVIDIA GeForce 8200M G, 160GB HDD
Today I decided to install the BURG bootmenu on my computer so that I could enjoy nice, pretty graphical bootmenus instead of boring old text-based ones.I installed and configured BURG using this tutorial(after some few snafus wherein I tried to use older tutorials and went through many needless complicated steps that didn't end up working anyway).Restarted, and it worked great - except for one thing. Windows would no longer boot.It would get to the "Starting Windows" screen, then about halfway through there it would flash and restart.It wouldn't start in "Startup Repair Mode" either (the same thing happened). So, I did some frantic googling, and discovered this thread. I followed a set of instructions posted therein to install Lilo, reconfigure my MBR to Windows' liking, and reinstall Grub2.Windows booted after that.Well, I thought that the problem must have been caused by one of the numerous false starts I made while trying to get BURG installed, so I installed BURG again, set it up again, and bang - Windows wouldn't boot any more.So, I re-did the MBR with Lilo again, only this time I forgot to reinstall Grub2 (oops!) and had to boot from my LiveCD and install it thataway.At any rate, I'm fairly certain that installing BURG is what's keeping Windows from booting.
Ubuntu Servers :: Acpi=off Flag Prevents Server From Booting
May 2, 2011I'm running Ubuntu Server 11.04 on a home PC as a local-only file and web server for some private projects.After a few minutes Ubuntu will stop responding to the network and a cold reboot is required to re-enable the NIC.I've been able to stop the above occurring with a user logged in and constantly pinging the gateway, although this is obviously undesirable.
I read here and elsewhere that a fix is to set acpi=off in grub. I have done this but now instead Ubuntu will not boot and shows the message:
do_IRQ: 1.55 No irq handle for vector (irq -1)
Disabling IRQ #34
and hangs there indefinitely. The system will boot fine if I revert the changes but obviously the sleep problem remains.The BIOS does not have an option to disable ACPI, just select S1 or S3.Is there anything else I should be looking for in order to disable sleep? Otherwise the system is working fine, and when it's awake I haven't had any other trouble.
Debian Hardware :: Unlocking AMD Cores Prevents Booting?
Nov 22, 2010So I recently built a gaming computer, which I typically use windows for. I'm mainly a linux user and I have separate computers for that. But, I wanted to try an experiment with linux on my gaming computer due to it having the best hardware I have.Anyways, I have an AMD athlon II x3, with the 4th core unlocked. Windows will boot up and use it just fine - it considers it a phenom II x4 b40. However, linux will not boot up as long as that 4th core is unlocked. grub is responsive but once it begins booting, it doesn't really do anything. its not just debian, its any linux distro.
i've never heard of linux having problems with core unlocking, and i have a pretty good motherboard (one of the top 5 socket am3 boards). i'm also very surprised to see windows somehow manages to accept this but linux doesn't.

Ubuntu :: Sporadic Grub Error 18 Prevents Boot
May 12, 2010In the past month or two I've run into a strange problem where Grub gives error 18 "Selected cylinder exceeds maximum supported by BIOS". Strange because:
1) after a few tries it mysteriously starts working again without any change on my part
2) I am not running a dual boot system, which seems to be the usual cause of this problem
3) though I have SATA hard drives, I have the RAID capabilities disabled in the BIOS, which can also apparently lead to this problem.
I'm currently running lucid but it also happened once before I upgraded. It seemed to start happening not too long after I installed a new 1TB drive, though that drive is only mounted under /mnt/backup, and not anywhere else of importance, so it may be a coincidence.
Here are some specs on my machine:
BIOS is ALive NF6G-VSTA P1.80
I have 2 SATA drives (no IDE drives except DVD-ROM):
/dev/sda is a 200GB Samsung drive with two partitions
- sda1 is about 197GB and includes / (including /boot)
- sda2 is about 3GB of swap
/dev/sdb is a 1TB Western Digital Drive
- 1 partition mounted at /mnt/backup
If the problem is that I don't have a separate partition for /boot, shouldn't the error show up every time I boot, not just once in a while?
Hardware :: External Hard Drive Failure / Not Displaying "booting GRUB" Or Any Other Signs Of Activity?
Jan 6, 2010I accidentally deleted the linux mint 8 that was on there due to a small issue discussed on another thread(long story followed by a stupid mistake). after then i reinstalled linux using the .iso i found on the website. all is well. I boot up linux on the external and it runs great. then i turn off the laptop and try to plug it into another laptop( which i used the external hard drive on before and worked) and it went through the bios screen but then after slight lag(5 seconds longer then usual) the blinking cursor in the top left corner would not display anything, anything meaning "booting GRUB" or any other signs of activity. after waiting some time i quit and tried it back on the other laptop, which it was just working on, only to get the same result. I am confused about why it would work the first go around but nothing past that.
The only thing i altered on the external after i installed linux was that i put my home directory into it( from another version of linux mint)
Ubuntu :: Booting From NForce FakeRAID - Hand Correct Grub.cfg After Update-grub?
Mar 5, 2011I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?
Fedora :: Can't Dual Booting With Grub (legacy) - Black Screen Grub Error 27
Jul 31, 2011is it ever possible to do dual booting with grub(legacy) ever at all!. it is possible provided i take some pain, here is the link of that post [URL] i was coward and weak i didn't try that out then. but i did try it out. now so if u haven't seen the post .... I've installed Fedora 15 desktop(Gnome) with physical Logical volume called vg_fedora lv_root(ext4) ,lv_swap and lv_home(ext4), with 500MB /boot partition and had about 200GB free hard disk space ... so i wanted to install Scientific Linux 6.1 (because our school uses RHEL 6.1)
so, while running the installer I made (added) a logical volume lv_Scientific with ext4 FS and made its mount point (/) and used the MBR /boot which overwrote the Fedora /boot (completely OK and was as expected) i restarted after installation i got SL log in and as per the directions of the thread i copied the boot stanza from grub.conf of fedora 15 (which i already had copied and pasted into a text file and copied it from there)and pasted it into grub.conf of SL you may ask why did i choose same physical LVM too save swap space ... if i had made another physical LVM i had to make another swap ( i like LVM ... its cool)
completely unexpected happened Fedora now boots but not SL when grub starts i get this error 27 unrecognised commad and when i press <enter> i get grub menu with SL and fedora when i press on Fedora it works well i get my fedora login and i did login .. everything works fine but when i press SL it goes to the previous black screen grub error 27

Ubuntu :: Grub Messed Up - Error: Can't Find GRUB Drive For /sdd1
Jan 31, 2010I've trawled the internet but can't seem to find the exact same issue, so I've made a new thread. So, I installed Ubuntu onto a 160gb drive. I have other drives in the system, but I disconnected them so that the system drive would be sda. Ubuntu installed perfectly with no issues whatsoever. I connected the other drives in the system, and again it booted up perfectly (although I can't remember whether the 160gb drive remained as sda or became sdd). Then I attached some extra drives temporarily to do some data shuffling.
This moved my system drive to become sdf. My computer booted fine multiple times like this, but when I was finished with the drives I rebooted and suddenly everything broke. For some reason my ubuntu installation showed up in the GRUB twice, and neither of them booted. So, I popped in the Live CD (which I'm using to type this post), and decided to update the grub. I chrooted into my system drive and ran update-grub, but it simply returned something like this:

Ubuntu :: Booting Windows Iso - GRUB?

Apr 13, 2011I have a working server running CentOS 5.5 (similar to RedHat EL) with the 2.6.18-194.el5 kernel. The hardware is a few years old, but we were able to accomplish this following goal using CentOS 4.4. What I'm trying to do is to back the system up to an external USB hard drive such that it can be booted from for recovery or to then take that drive and restore its contents to a second server with identical hardware. We have been successful implementing this on other server pairs, but I'm having a great deal of trouble getting this to work on this hardware and OS. I'm not using LVM or dual-booting with another OS. The USB drive is set up with identical partitions to the RAID set, and all the files have been successfully copied over, but I can't get the system to boot from it. Below is what I get when trying to boot from the USB drive:
Code:

Ubuntu Installation :: Booting And APT Upgrade Of Grub?
Jan 17, 2010OKI am loading 9.10 (K or U, makes no difference). This installs 2-6-31.14. Eventually I am unable to dissuade APT from upgrading to Grub 1.97 beta4. One of two things can happen.
1) I am upgraded to a later kernel at the same time (currently 2-6-31.1. This singularly fails to work, in that I end up with no working kernel at all and I can only run memtest (or Windows 7, which is about as much use): good for the soul no doubt, but frustrating. "Solution": tar up the whole of /boot beforehand and then reinstate it afterwards. I am back to square 1, but at least a working square 1.
2) I persuade APT not to upgrade the kernel.I then get 14 (and 14 recovery) in my grub.cfg, but boot fails dramatically, and it becomes apparent that it has forgotten about /dev/sda, my hard disk.Further investigation shows that I have a new initrd.img in /boot, which doesn't work properly; reinstate the backup version, and all is well.What is going on? Is it just me? How come there aren't crowds of protesting peasants with pitchforks outside Canonical Towers?
Ubuntu :: Booting Hangs At Grub Menu?
Jan 19, 2010not related to this thread [URL]
On a few VMs. Sometimes, when powering them on I get the GNU GRUB menu...
Code:
GNU GRUB version 1.97~beta4
Ubuntu, Linux 2.6.31-14-generic
ubuntu, Linux 2.6.31-14-generic (recovery mode)
Memory test (memtest86+)
Memory test (memtest86+, serial console 115200)
etc
But there is no countdown for a default boot. It just hangs here. Indefinitely. Until I make a choice by pressing the enter key with "Ubuntu, Linux 2.6.31-14-generic" highlighted (default). I don't know if this is because the VM may not have been shutdown properly or what the case is, but this is unacceptable as I need these systems to continue to boot and get back on line regardless of the reason they were powered off.
