Since this morning my system refuses to boot Ubuntu 9.04 installed in Vista using Wubi.It has been working for months, but now it fails to start. I get to the windows bootloader screen. When booting Ubuntu (pre-selected) it goes straight to GRUB. Performed test several times: it is consistent.
View 7 RepliesI've recently reinstalled all the os's on my computer, just now I'm going with ubuntu (general use) win xp (for flash, it doesnt play nice with 7 for some reason) and win 7 (for games). Everything is fine, but I can't get grub to boot me straight into either of the windows versions: Each option makes brings me to the windows bootloader, where I can choose between "Windows 7" and "Older version of windows". I want to go directly from grub to xp/7, without that extra menu. How do I get rid of it?

I was running a ubuntu server on another PC which has no keyboard. only power and lan cable is connected and i was remotely admining it from my desktop PC. When i turned that Server PC on earlier , it goes straight into user login screen of ubuntu server. But right now i see the grub menu list which is expecting the keyboard Enter input. how do i remove that so later on i don't need to plug the keyboard and hit enter to goto server login ?
View 4 Replies View RelatedI tried to install Ubuntu as a dual-boot on my Windows XP machine, using the USB stick trial OS and automatic installation. My screw-up came when I left my external USB hard drive plugged in during the install, and as far as I can tell, Ubuntu was installed on that as opposed to my internal HD. Now when I try to boot, I get knocked straight to the grub rescue prompt with an error message that basically shows my "no such device (my external's ID)" -- assuming that the MBR (which I know nothing about editing) is trying to boot off the external that isn't actually enabled until an OS starts it up, and dumping me at the rescue prompt when it can't find it.
I can still load up the trial Ubuntu off the original USB stick (though can't get online with it without wireless drivers), but that's as functional as the computer gets right now. And I don't have a Windows Setup CD anywhere (using a rooommate's Mac at the moment with a terrible European keyboard on it). So is there any way to edit the MBR or something to tell it to boot my regular XP off my internal HD, at which point I can re-partrition and try this whole thing again, or otherwise remove the failed install of Ubuntu through the trial-stick or... well, I'll leave the suggestions up to you all. I've been working on this since about 4am last night and my brain is kind of fried.
I was dual-booting Vista Business and Fedora 12 on the same hard drive. I deleted the Fedora partition and expanded the Vista partition to use this space.
I figured that because GRUB was on the Fedora partition (at least, I thought it was), I'd just be able to load up Vista as usual.
When I turn the computer on, a GRUB command-line comes up, and to be completely honest, I have absolutely no idea what to do at this point. I'd quite like to just get rid of GRUB entirely and boot straight into Vista, but again, I don't know how.
I've tried using a Vista recovery disc to sort out startup problems, but it doesn't do anything because the problem occurs before control is passed over to Vista.
What can I do to fix this problem? Can I get delete GRUB and boot straight into Vista? How?
I upgraded from Meerkat to Narwhal. After all the files have been downloaded and installed it rebooted. Once it rebooted it went straight to the GRUB command line. After couple of hours of research, I ended up at
[URL]
My root was at (hd0,1). So therefore I put this in at the GRUB prompt.
set root=(hd0,1)
linux /vmlinuz root=/dev/sda1 ro
initrd /initrd.img
boot
I did what it said and it got me into Ubuntu. Nice! It asked me to: After successfully booting into the system the user should run sudo update-grub I did. Next it asked me to review (/boot/grub/grub.cfg). That's where it is hairy, my file has multiple root settings and with msdos settings. That doesn't seem normal.
[Code]....
I 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?
is 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

Not sure if this is the exact right spot for this post, I've got an .ISO file of windows 7, but no DVD's to burn it to. I've read that I should be able to use GRUB to boot, but I can't exactly get it to work. I've been poking around the map function trying to sort of mount the iso somewhere within the hard drive, but I'm not sure if that's how it should be done.

View 6 Replies View RelatedI 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:
Booting 'CentOS (2.6.18-194.el5)'

OKI 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?

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.
I'm relatively new to Linux and I am dual booting Ubuntu 10.04 LTS and Windows XP and I would like to edit my GRUB menu to allow me to choose Windows XP which is on a 2nd hard drive. But, I can find no menu.lst and there is no GRUB menu while booting up, my computer boots right into Ubuntu. So, how do I enable the boot menu so that I can edit it and use it?

I have two versions of Ubuntu on my computer - 10.04 and an earlier one that i no longer use. I'd like to free up the space that the old partition is taking, but the computer boots from the grub menu.lst of that old version. How can I make the boot process use the menu.lst in the 10.04 partition?
where is the boot process situated anyway and how can you get at it?
Every time I use GRUB to boot into Win7, I can't reboot back into GRUB or Windows. I think Windows is forcing itself into the MBR then proceeding to corrupt it. I believe I can just boot into a Live session use "sudo grub-install /dev/sda", but that seems like a lot of work just to reboot.

Are there any viable workarounds? For instance would installing to the primary disk, copying to the other disk, and then using chainloader to point directly to ntldr work?
Update Manager showed updates available so I installed them about 1hr ago. When the update was complete I clicked the "Reboot to complete installation" button.

While trying to boot ubuntu, I noticed that it was taking a long time. A lot longer than usual, in fact.I then forced a restart on my computer, and noticed that Grub looked different - the resolution was weird.I then tried again to boot ubuntu, and got the following messages:vga=792 is deprecated. Use set gfxpayload=1024x768x24,1024x768 before linux command.mount: mounting /proc/ on /root/proc failed: Input/Output error.And then the computer seems to stay idle forever.Recovery mode is also not useful: I can only see some periodic messages about a failed command: READ FPDMA QUEUED.
However, I also noticed that grub showed something before it allowed me to choose which OS I would like to boot (Im running a dualboot configuration with Ubuntu 10.10 and Windows 7).I managed to get it:error: hd0, msdos6 out of diskerror: no suitable mode foundConsidering that I have no trouble booting into Win 7, and that I can actually access my Ext4 partition from there, Im trying to reinstall Grub from a Live CD.Heres the output of fdisk -l :ubuntu@ubuntu:~$ sudo fdisk -l
