View 2 RepliesIve installed Ubuntu 10.10 from a SD card (yes my laptop supports booting from SD) and it works fine except the grub does not load. Although I know there are many threads about this Im not sure which one to use because my problem is quite strange.
Im not pretending I understand how grub works but I find it strange:
When I boot from Hard Drive, it boots into Windows without loading grub (I installed ubuntu to an empty partition along the windows on the same drive), however, when I force booting from the SD card, I get the grub window with all the options as expected - ubuntu, mem check, windows 7. Now Im not sure if its grub loading from this SD card (containing ubuntu) or the card somehow runs the grub that is on the hard drive.
My guess is that the partition containg windows (sda0) is flagged as boot and thus the system doesnt even look after grub when booting, however, when theres the SD card it somehow forces booting the ubuntu partition (sda6).
Any idea what I should do? I can boot into Ubuntu, I can access grub etc. I just cant make it load without having the SD card in my PC
i am newer to linux.i have a doubt in linux boot process in my machine RHEL5 has installed,in bootig GRUB will load in 3 steps
stage 1--> stage1.5 --->stage2
stage1
1st stage1 of grub is located in the 412 bytes of MBR)
also there is a file
/boot/grub/stage1 ( then what is this???)
stage1.5
( where does stage1.5 file located ? i found certain files in /boot/grub/)
like
e2fs_stage1_5
fat_stage1_5
ffs_stage1_5
code....
but my qusetn is GRUB loads from among these files??i removed the above mentioned files from /boot/grub ,but my system is still booting!!!!!!!!!!!!!!!!!!
how it is?then how stage1.5 and stage2 take place??
I do not know what to do, i cannot load windows partition. it just loads grub again. this must have been something that happened when i upgraded to the 10.04 or w/e. can someoen help me out with what i can do to stop this or fix it. maybe i can reinstall but i want to know what will work first, i do not have a lot of time to fool with my computer like this again. i spent a week getting ubuntu on my computer the first time so i do not ever want to spend that much time again especially in finals week. !

View 9 Replies View RelatedI have an odd issue -- fairly fresh Debian Testing install, using Lightdm.
After booting up, Lightdm starts, and then a moment or two later restarts. As a result, any keystrokes captured by the first run (e.g. the first few characters of my username) are lost. My lightdm log is:

This log shows me seeing the login screen, waiting for it to restart, and then logging in correctly on the first attempt.
I have recently downloaded and installed Ubuntu 11.04 inside my copy of Windows. When I boot my laptop, I have the option to either boot in Windows or Ubuntu. When I boot in Ubuntu, I get the login screen all OK. But when the screen loads up, it is missing the top and left hand side navigation bars. It then appears to be trying to refresh itself (unsuccessfully) as after about 30 seconds the screen goes black and then the wallpaper image will come back, still without the navigation bars. This keeps on happening until I reboot the machine. The only way I can get the screen to reboot OK is to run the repair option on boot up.
I have notices that after the above has taken place and I have finally got the system to boot all OK by running the repair option, the system will not connect to my mobile broadband via the USB dongle. Not sure if they are related, but at this point they seem to be.
I've been using Ubuntu for more than a year (just basic simple stuff like surfing the net or the occasional document) and in the last months I've been running into the following problem.I've been updating regularly to the latest Kernels the last one should be 2.6.32-25. However at start up Grub loads only 2.6.31-19 and below and there's no mentioning of 2.6.32 in grub.cfg while it is present in menu.lst. I tried to update grub with no success.

Once the system is running, I can reboot back into Xubuntu but if I power down GRUB does not seem to load. I've got the system to power on at 8am every morning but the fact that I have to reboot it is really annoying me.
Update:
Reinstalled GRUB to the master boot record of my first hard disk and it solved everything. I had to follow the second part of this guide to get it to work:

I've installed Ubuntu inside Windows 7 with the Ubuntu Windows installer. I have previously had problems with booting Ubuntu, but it always got to GRUB at least. Now it shows the Windows bootloader, I select Ubuntu and the computer just reboots.
View 4 Replies View RelatedThe problem is I've set up a dual boot with Xp and Ubuntu 10.04. Ubuntu was working fine till 2 days back but now when I select Ubuntu from the grub screen i get a whole lot of numbers next which it'll say Usb drive or sd card reader etc.. these go by quickly and then the comp stops running. If i press enter on the keyboard I get Initramfs and then i can type but nothing happens even if I type reboot. if I press cntrl+alt+F2 then i get a blank screen with flashing cursor. Same with recovery mode. Windows boots fine. The grub2 screen comes fine. The last thing i did before this happened is reconfigure the grub2 screen, but it seems to be fine (i had added a background img and reordered the boot options) I did not edit grub.cfg. I would prefer not to reinstall it as iv done it a half a dozen times already in the last few weeks..

View 4 Replies View RelatedMy problem is that last night, when I was watching some .swf file in firefox, the computer slowed down to the point of my not being able to do anything about it. I shut the computer down and restarted to handle the problem. This worked the first few times, and proceeded to really turn out bad later on.
Now, I have windows and ubuntu on the same hard drive. Whenever I select ubuntu, I get a message saying "GNU GRUB version 1.98-1ubuntu8" and some stuff about how limited Bash-like commands are supported. I can also his tab to do stuff. By using the help command for everything, I have determined that the command "linux" is supposed to load linux and "boot" is supposed to load an OS. Everytime time I pick a command that should load something, it says that I need to load a kernal.
I'm getting a tad frustrated. Having gone down a dead end on this thread: [URL] I reloaded 10.10, wiping out previous install. Everything was working as it should. I then updated (today, Sept 16, 2011) When rebooted, the system went right to a grub prompt.
View 9 Replies View RelatedWhen I boot my pc it used to take me to a prompt which asked which OS I would like to boot. Today randomly, some grub rescue menu came up. I read online that that meant I had to fix my grub menu, which I did. Now a regular grub menu pops and and I have no idea what to do with it. Whats a grub menu? How can I just get back to my regular boot screen? I run dual boot xp and ubuntu, is grub a program of xp or ubuntu? I have no idea what this grub menu is and whats going on with my pc!
View 2 Replies View Relatedi just installed the Debian on my old laptop. The install went fine but after that, the GRUB menu loads and freezes. I simply can't do anything. I checked menu.lst and the timeout is set to 5 but still nothing happens. It won't load. I then tried to load with the "super GRUB disk"but the same problem - as soon as it loads from the CD, it freezes and I can't do anything. Before I had Xubuntu on the same laptop but there was no Grub menu. It simply loaded. There's only 1 OS on the laptop /currently Debian/ - no windows, no other Linux.
View 14 Replies View RelatedMy Wubi installation of Ubuntu (version 9.10, I think) that I recently installed was working fine at one point, but now it isn['t. I select Ubuntu instead of Windows from the Windows boot loader, but instead of getting the usual menu of different linux versions (I think 2, as I updated it at same point), and Windows, I get the GRUB command prompt instead.I've looked at th2e Wubi Guide (https://wiki.ubuntu.com/WubiGuide), and I've followed the instructions for "How can I access my Wubi install and repair my install if it won't boot?", but that reveals no problems.For the record, I'm fairly new to linux and ubuntu, but I'm good with computers generally. The main operating system on my computer is Windows Vista, but I'm currently typing this from a Live CD of Ubuntu 9.10. The virtual disk (root.disk), is currently mounted as vdisk, as indicated in the Wubi Guide.
Ideally I would like to get Ubuntu to load as it used to (with a menu). However, if there is a way to boot from the GRUB command line that would be good too. I'm not at all familiar with GRUB, and the commands I've tried (boot and linux, I think), get errors saying no kernel specified, or loaded, or something like that.
I've installed Ubuntu desktop edition 10.04 so far, using alcohol tool as I wanted to install "inside Windows".I successfully installed it everything seems to be fine to me. But, the problem is when I select Ubuntu from boot menu it stops at a console with some grub loader message and doesn't shows login screen.
Please, not that I had installed it a couple of time before and it worked perfectly for some reason and Windows problem I had to uninstall it.
I can also post pictures of that screen if you require, I've to capture it through my mobile phone, which is with suck graphics.
Message:GNU GRUB version 1.98-1ubuntu5
I performed a clean install of Fedora 15 from DVD and it goes fine until the end when the install program says to reboot the computer. Once I do that, the computer hangs before Grub loads, i.e. just after all of the BIOS messages, so there isn't any error message to indicate what is wrong. I had no issues with Fedora 14.
View 3 Replies View RelatedI 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

tried startx again, got me an error. found something that said add "vga=ask" to the grub loader, which still loads into shell, but when i do startx, it made me a xorg.conf.new, which i copied into /etc/X11 rebooted and tried again. still have to move the mouse or keypad for the load to start (no idea y) but it loads to shell, and startx works.

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.
