I updated Ubuntu and part of it was an update to grub. When it came up in the installation I told it to keep the old one and left everything as it was. Then when I tried to reboot into Windows it gave an error message. So I went back into Ubuntu and reinstalled grub and now when I select Windows it just loops back to grub.
View 4 RepliesI just upgraded to 10.04 from 9.10 and when I choose to boot to my Win7 Pro it just loops back to the grub menu. I did choose the partition that Windows is on when I was upgrading and it shows up in the menu.
View 3 Replies View RelatedA few days ago I installed openSUSE 11.4 on a 1TB HP external hard drive. I have some very important files for school and personal work on my main hard drive, running windows 7, so I made sure the installation only affected my external hard drive. With the external hard drive plugged in it boots just fine but when it is un-plugged it says Grub loading stage 1.5. Error 21 and it won't do anything. This kind of pisses me off because there were no warnings and nothing was supposed to happen to my main hard drive. But this has already happened and now I want to know if there is any way I could fix it so I can boot windows 7 normally and still boot openSUSE with the external hard drive plugged in.

When I try and boot my Debian computer I get the messages: Grub Loading stage1.5. Grub loading, please wait... Error 15 Is there any way of recovering from this - or is it simply a fresh install? I was attempting an upgrade from Lenny to Squeeze and despite a few hurdles it looked like it was all happening. Got the new kernel loading, and the new grub. It looked as though grub2 was working so I ran the grub-remove-legacy-support command (something like that) and now my computer won't boot grub or Linux.
I'm assuming the MBR on my harddrive is lost, however I don't know what state the partition is in. I'm guessing that maybe this has been lost as well. I tried a few tools from the Ultimate Boot CD but nothing here was able to re-install my grub or boot from any partition or even mount my file-system. I'm fearing the worst but would like it confirmed before I blow it all away with a new install.
Ubuntu 10.04 not loading. Sticks at GRUB Loading message.
Read the other threads re OS not loading and GRUB. The talk about code goes over my head.
Local techie says the hardware is good. Tried reloading Ubuntu from CD. Tried loading the unmentionable OS.
Tried using Spotmau Powersuite.
I have 2 hard disks. sda,sdb
In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD
Chose advanced istall
Selected sdb3 for Ubuntu
I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.

I have installed the ubuntu 9.10 and the pc already have 2 win 7 OS and 1 win xp I installed the ubuntu from win xp every thing go just fine but in win 7 boat loader it detects the 2 win 7 OS , previous windows ( the xp )and the ubuntu which fails to load from win7 boot loader ( the first problem ) but it is present also in win xp boat loader so when choosing older windows the win xp bootloader let me choose between windows xp and ubuntu which works fine when choosing it the ubuntu bootloader appears with ubuntuubuntu safe modewin7 bootloader
the second problems that choosing win 7 after restarting the pc from ubuntu fail to open it begin loading with the windows logo and then just shutdown the whole pc as if i have unplugged it! the only way to let it open is to choose older windows>>> ubuntu >>>> ubuntu bootloader >>> where there is win 7 bootloader option it returns me again to win 7 bootloader but this time the windows load complete ( mostly but may shut down also!)
I know nothing about this at all. I have never programmed a computer.. I loaned my tower to a friend who put this on ...now i have it back and cant get to my windows 98. all i get each time i boot is ...

I have an Ubuntu Jaunty server with 4 x 1 TB Hitachi SATA Hard drives and a 4GB IDE Flash Drive. I installed the root file system to the IDE Flash Drive and setup the 4 x 1 TB Hard Drives as a RAID 5 for the home partition (I actually allotted 3 Gigs on each drive as swap space as well). My problem occurs however when I restart my computer after the server installation. Grub doesn't load fully and I am left with a "GRUB_" message on the screen.My root partition is ext3 and I have also tried the same configuration with a boot partition as well on the IDE drive to no avail.

View 2 Replies View RelatedI finally got it and windows 7 installed on separate hard drives. Windows installed first, then ubuntu 10.04.01. Had to use the alternate ubuntu install cd to make it work. During the install it said there were no other operating systems installed on the computer and asked if grub could overwrite the master boor record. I knew this was something I wanted to do and if it was wrong it could most likely be fixed later. So that being said, ubuntu has taken over the boot of my pc. No grub menu pops up. Not sure how to add windows to grub to make it give me a choice. I did try pressing shift during startup to get grub to load, and nothing happened.
Here is my fdisk.

I set up a dual boot system with Win7 and Ubuntu 9.10. Ubuntu is the first OS listed in the boot menu. I would like to change the boot order so Windows is first. Also after running a few updates I now have multiple boot items listed for Ubuntu that I'm sure are no longer needed. Having never edited Grub and searching through the forum, I'm asking help. I going to guess that I want to edit grub.cfg. If so, what do I need to change within the following information?
[Code]....
Looks like Grub2 on my new installation of Ubuntu 9.10 is not picking up a Windows 7 installation on a RAID0 array (using the built-in RAID software from my Asus P5Q-Deluxe)
Here are the results of the boot info script:

I had XP Home on my dual boot Ubuntu 10.04 LTS amd64 PC & now installed Window 7 Home Premium 64-bit over old XP. Before installing Win7, as a precaution, I disconnected the hard drive where Ubuntu is installed. Now, naturally, the startup screen (grub?) still offers XP. Is there an easy way to re-detect & rewrite the startup menu with the Ubuntu install CD without re-installing Ubuntu 10.04 LTS amd64 again, like a GRUB repair or rewrite?

I have a major problem with Windows 7's MBR. I deleted Ubuntu's partition last night, and when I restarted, I saw:
Code:
error: no such partition
grub rescue>
I looked it up, put some code into a LiveCD terminal, and I thought it worked. But now, I says that I definitely need to put in a Windows 7 CD and do that MBR fix method. I did not own a Windows 7 CD; my laptop came with it pre-installed, and I have no recovery partition anymore.
I have Win7 installed in my notebook, after I install WinXP, after I install Ubuntu 10.10
I need WinXP to my project...
I re-install Grub2 with live CD and the WinXP doesn't show up...
So I re-install WinXP... Re-install Grub2 and WinXP doesn't show up again...
So I custumise Grub2 and I put one line for WinXP (doesn't work)
But Now, Win7 line in Grub2 boot WinXP

My tech savvy friends built me a computer and put win7 64 bit and then installed ubuntu (upgraded to 10.10) and had grub so whenever i turned my computer on i could choose between linux and windows and everything was fine. The other day i couldn't boot into ubuntu so i went into my win7 partition and deleted ubuntu and all other partitions and/or extensions thinking that it would get rid of ubuntu. Now when i boot it doesnt recognize anything so i tried booting from my ubuntu cd (don't know if its 10.4 or version) and it will load and when i try to install it i get the grub recovery thing and then the initramfs thing and the error "initramfs Can not mount /dev/loop0 (/live/image/live/filesystem.squashfs)"
i don't need ubuntu but i do need windows as it has files and papers that i need this week.
I've resized partitions with some program - perhaps even gparted - but from Win7. partitions are indeed resized, but now I can't boot Win7, grub says:
"No such device found - No such partition found".
I tried to use some advices on similar problems I found here (like adding GRUB_PRELOAD_MODULES="part_msdos" to etc/default/grub and running grub-mkconfig after), but nothing helped. I guess I could restore win7 with installation dvd but I want to fix GRUB (and have both ubuntu 10.10 and win7)

I want to know about grub. Let start with the explanation of grub. I am using Ubuntu 10.04. Yesterday when I installed widows7, I lost my grub. Every time I tried to install windows running on Ubuntu machine, the grub is lost. Why is it so? How can I restore it (for Ubuntu 10.04)? Can any advance setup be made while installing windows, so that the grub is not lost?
View 3 Replies View RelatedI had Windows 7 and Ubuntu 10.1 installed in my intel i3 4gig DDR Sony Vaio E-series laptop. Both operating system were working fine. Only problem that I used to have was the sound didn't use to play when I boot through Ubuntu. Due to that, I formatted the corresponding drive from Windows in which there was Ubuntu installed. I used "diskmgmt.msc" to delete the partition and then format it. The format was successful and when I restarted my computer, this error was displayed:-
error: unknown filesystem

Windows didn't load at all. I used to have multiple boot grub menu previously before formatting the partition but that didn't show up after formatting.I am unable to use any of the Operating System.
