I hav two 40 GB hard disks.RHEL5 is installed on 1st and Windows on 2nd. In order to use each OS I manually hav to go and change the "first boot device" option in BIOS setting and boot into required OS. GRUB doesn't show Windows in its boot menu.How can I make GRUB recognize Windows and boot into both OS using GRUB boot menu?

View 5 Replies View RelatedI have just updated my Ubuntu linux to Ubuntu 10.4, not my grub menu isnt letting me boot to Windows Partition.The problem seems to be with grubs new update from using an editable menu.lst file to using a non editable grub.cfg file. Everywhere I look it states "DO NOT EDIT THE GRUB.CGF FILE". I am at a loss as what to do. I figured that the new configuration has screwed up the Windows Boot File. Anyone have any suggestions on how to fix this. I am not sure if it is a windows issue or an issue with the Grub boot menu.

I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows.

I have a Compaq Presario CQ60 with Nvidia GeForce 8200M graphics card. When I first installed Windows 7 followed by Karmic in dual boot I could boot into both OS. Now when I try to boot into Windows, it displays the Windows logo and then drops back to the grub menu. It may have started happening after Windows 7 installed updates. I tried reinstalling both Windows and Karmic again and it again worked initially but now Windows no longer boots. Does anyone have any suggestions about what may be causing this or how I can fix the problem without reinstalling?

i am having a problem with my dual boot setup. I originally installed windows XP on a 100gb hard drive, from there i downloaded and burnt ubuntu off so i could install it on my 200gb hard drive. For a little bit i struggled to even get it to install because it wouldn't recognize my onboard nvidia graphics, i ended up having to get an alt boot disk and fix it with technique in this link:

Now after the bios boot, my screen shuts off for awhile and takes me directly to the login screen for ubuntu. No Grub, no windows boot options, nothing. I tried booting windows by choosing it from the bios boot menu but all it does is hang at prompt and doesn't boot at all. I tried the live cd fix and reinstalled grub but nothing changed. What i think is happening is that it boots the Grub menu but it doesn't display it because of graphical confrontations. It hangs for about 10 seconds, the grub default time, and then turns my monitor back on to display the Ubuntu login screen.
I upgraded to Ubuntu 10.04 recently and now have MBR problem. When selecting Windows XP from the GRUB menu the screen defaults to terminal mode with grub rescue> displayed. I admit I know little to nothing about Ubuntu, unix, etc other than I like what I have seen so far and am trying to learn more. I need to (unfortunately) use Windows and have data on it that I can't afford to lose. How can I repair the problem so I can boot Windows from the menu? Thank you
P.S. I was dual booting successfully earlier. I had the previous version of Ubuntu running with Win XP and everything was fine. The problem started when I upgraded to Ubuntu 10.04. I have tried reinstalling 10.04 with no success. If I am unable to get dual boot working my wish would be to save my Win data and then I can wipe clean and reinstall Win and Linux.
It would be nice to get a sticky thread up for dual boot installation issues. It seems like this is a very common problem with the upgrade from 9.10 to 10.04.
I was finally able to solve my issue dual booting 10.04 and Windows XP Home at this thread.

I had to reinstall Grub2 and run update-grub.
Then I had to run Rescue on my XP disk. Once to the DOS command line I ran the following command:

I rebooted and now all is well. I can boot to Ubuntu 10.04 or Windows XP from my Grub menu.
Since upgrading to Lucid (I think), I can't boot into Windows. When I select the Windows Vista entry in GRUB, the screen goes blank for a moment before returning me to the GRUB menu.I have tried pressing 'e' to edit the GRUB entry before booting, and what I find is that it says the root is hd0,1Since my Windows partition is sda1 in GPartEd, should that translate to, for example hd0,0 ?The only reason I want to boot into Windows in the first place is to install a BIOS upgrade from HP, which only works with their Windows software. If someone can suggest an alternative way of doing this then I won't need to boot into Windows at all.
View 9 Replies View RelatedI installed Ubuntu as a dual-boot system with Windows XP very carefully. Unfortunately, though given the option to boot Windows at the grub menu, when I select it, I get an error. Booting Ubuntu on my other partition works just fine, no issues.
I also attempted to access files from the first partition in Ubuntu using gparted, but once I mounted it, all of my files were not present. I only saw manufacturer files, and many files and folders I didn't recognize.
Also, as an aside, my laptop monitor is suffering from occasional black-outs during use. Ubuntu gave me a little toolbar flag, telling me to go to a website and use the patches given to fix it, but I'm not quite so sure where to input the given patch text. Do I really need to go through the trouble of finding the source code, etc., or is it more simple?
I just got a Zino HD from Dell, and was planning to use it connected to my TV, dual booting Xubuntu 10.04 and Windows 7. I did, however, run into some issues. I suspect I'm just going to have to burn a restore disc and start over, but I'd like to fix this if possible. Here's what I had to start with:
1 vfat partition (bootup?)
1 dell restore partition
1 Windows partition
Because the restore partition was a bloody 20 GB, and I could always get the restore done via disc, I reformatted it as ext4 and used it as "/". I then shrunk the Windows partition and allocated a home partition and some swap space. Note that immediately after the installer, I reformatted the home partition manually with an inode size of 128 to use with the Windows ext2 driver, but that shouldn't have really changed anything. End result file system order:
1 vfat
1 ext4 mounted as "/"
1 Windows
1 Swap
1 ext3 mounted as "/home"
I now have two problems:
1) I do not get any GRUB menu at all! It just boots directly into Xubuntu with no choices (not even memory test or restore mode).
2) I, obviously, can no longer boot Windows.
Keep in mind that this a fresh install on a brand new machine; I can't think of any reason GRUB wouldn't even show me a menu.
How do I get "Windows Vista Home Premium" to show up in my boot menu? Right now is just says "Other". I am dual-booting.

I had Windows Vista installed on my computer and created a partition to install Fedora 15. I chose the option to install fedora on any free space, so it should have installed on the empty partition.

I've had two students report a problem whereby Ubuntu does not show up as a menu option in Grub. Both systems used Wubi installations of Ubuntu 10.04 Desktop for x86 on Windows XP. In both cases, Ubuntu completed the installation process. Upon reboot, we have the options to choose between Windows XP and Ubuntu. However, once we enter into Grub, only the Windows XP option shows.

I regularly update my ubuntu (10.04), and new minor versions keep accumulating on the GRUB screen. Right now I have 5 different versions listed on the GRUB, even though I always select the latest version to work with.
Am I supposed to do anything to get rid of the old version references? Do these old versions affect disk space/performance?
I had debian squeeze already installed, then installed win 7. Windows overwrote by MBR, as I expected it to, so I used an ubuntu live cd to reinstall grub2 to debian root.
I rebooted, and sure enough I had grub back. The boot menu has debian on it. Just debian (crunchbang actually, but its the same thing).
So I added a script in /etc/grub.d (called Windows_11) to create a windows chainloader entry in grub.cfg, and ran update-grub.
Update-grub picks up my /etc/grub.d/Windows_11 script, and adds an appropriate chainloader entry to /boot/grub/grub.cfg.
So I would expect this new chainloader entry to show up in my boot menu when I boot up. But it doesn't; on booting I only have the option to select debian.
Here is my /boot/grub/grub.cfg -
Code:
### BEGIN /etc/grub.d/10_linux ###
menuentry 'CrunchBang Linux, with Linux 2.6.32-5-686' --class crunchbang --class gnu-linux --class gnu --class os {

i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

Whenever I start up my system, my BIOS'es load and do their thing, and then hand the show over to GRUB, which is supposed to not appear or do anything because my GRUB countdown is set to 0, but instead I get two errors like this that appear for about 5 or 10 seconds (greatly delaying startup) and then Xubuntu, the first entry on my Grub menu, loads: (I set GRUB to automatically boot my first entry):

3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?
Have just installed 9.10, again, many failed attempts previously.Cannot get to boot up and show menu on dual boot with Vista initially,However when I delete the grubenv file the system boots ok and works fine.But does not show the grub menu to choose boot up choices.Got the information to delete the file on some posts elsewhere about booting problem, and tried a longshot and got into Ubuntu for the first time from trying to install now for 3 months!The problem is the file grubenv is created each time so on subsequent boot ups the sytem fails to boot again.The Grub version is 1.97 beta 4, most up to date for Karmic I think, I have seen a version 1.98 but dont think its for Karmic?
Is there a way to modify the grub.cfg file to stop this problem ( all posts say dont touch this file??Or install a script to delete the grubenv file on shutdown as a workaround for me, (I have no idea how to do this whatsoever, I'm not familiar with linux at all)I did read that this problem was fixed/patched in Grub version 2, but dosn't seem.so on my system afetr I updated it when I got into Ubuntu.I couldnt find the patch or fix, I got the information I am on about from this post:URL...It seems to say it was fixed or patched by Colin Watson reading through, but I don't really understand whats being said or how to get the patch on my system if indeed there is one?Sorry for being a bit thick about all this, its a bit beyond my brain now, hope somebody can help out as I have enjoyed my brief bit of fun in Ubuntu.

I have a problem with my GRUB bootloader. I have Ubuntu 9.10 and Win XP installed on my laptop. But only the list of Ubuntu appears in the menu and NOT win XP.
Some instructions say try to edit the "menu.lst" file in "/boot/grub/" menu.
But there is no such a file in my /boot/grub/" folder.
