I tried to re-install Ubuntu on the newly formatted partition but this won't work, because after removing the install-usb (which I am said to do during installation) I find the above error-message again. I guess I need some way to reconfigure grub OR to reinstall grub/ubuntu (on the newly formatted partition) OR to reinstall the windows boot manager (without reinstall. Windows), but I have no idea how to do either of these things. boot command-line grub2 boot-failure bootloader share|improve this question asked Mar 19 '12 at 12:41 qwBJ 1612 add a comment| 3 Answers 3 active oldest votes up vote 3 down vote GRUB, as installed by Ubuntu, won't work without access to the Ubuntu partition. The easiest solution is to reinstall windows bootloader. You should start your computer with the windows installation disk, select the repair option, select the command prompt repair. Type: Bootrec.exe You can install Ubuntu afterwards. share|improve this answer edited Mar 20 '12 at 11:17 answered Mar 19 '12 at 13:05 Javier Rivera 25k56495 Are you sure that GRUB won't work without Ubuntu?

Now I logged on to Windows, opened the partition editor and deleted the volume containing the Ubuntu - I thought it will delete the Ubuntu and it might help me install another OS - and I restarted the system. GRUB rescue prompt is there. I want to log on to Windows. How can I http://unix.stackexchange.com/questions/71555/boot-windows-from-grub-rescue-command-prompt do that? In GRUB rescue, I tried the following: ls (hd0) (hd0,3) (hd0,2) (hd0,1) (hd1) (hda1,1) Tried all combinations of ls (hdax)/, which threw out: error: Unknown Filesystem. I tried this: rootnoverify (hd0,0) chainloader +1 makeactive boot It threw out: Unknown command. EDIT: I installed Ubuntu from the USB. Now when I restarted the system, I got the GRUB, showing old Windows and the newly installed Ubuntu. I happily logged onto Windows. Then I used standard procedure to remove Ubuntu, so as not to have grub rescue. linux windows grub rescue share|improve this question edited Sep 1 at 9:24 Josip Rodin 55319 asked Apr 7 '13 at 6:19 Karthi prime 1101311 add a comment| 2 Answers 2 active oldest votes up vote 19 down vote You can't boot Windows from a grub rescue prompt, unless the partition with the grub modules is available. That's why you get the unknown command error. Your best solution is to reinstall the Windows bootloader. To do this boot from a Windows 7 repair CD or the Windows Installation DVD to a repair prompt and run: bootrec /fixmbr If you don't have a Windows repair CD or Installation DVD, it's also possible to install a Windows-like bootloader from an Ubuntu CD/USB if you have one of those: sudo apt-get install lilo sudo lilo -M /dev/sda mbr Note that lilo will popup a large

Can't boot into Windows 7 up vote 6 down vote favorite 3 I am confused, so I am also going to use this question to get clarification and fix my computer. Some background: I had Windows 7 on a 1 TB HDD and decided to partition my boot windows 7 hard drive into two ~500 GB partitions, one for Windows 7 and one for Ubuntu or whatever flavour I desired (like a sandbox partition...) I installed Ubuntu but the installation had issues so I decided to uninstall. Note before the uninstallation I had to press f12 when I turned on to boot from my primary HDD, then choose what OS I wanted to use. Undesirable, but it worked. Anyway, after I decided to uninstall Ubuntu I went into Windows 7 > Start > Computer > Manage and deleted the EXT4 filesystem (Ubuntu partition) giving me 4xx GB of free space. However when I restarted Windows 7, I am now unable to boot Windows. When I DON'T hit F12, I see a blank screen with a flashing underscore. When I DO hit F12, I choose my primary HDD, and then I get a GRUB error: Unknown filesystem: grub rescue> _ Something I'm unclear of: GRUB boots linux partitions, right? What boots Windows? Is GRUB "overwriting" the Windows bootloader? How can I completely get Windows back to normal? (IE, It boots automatically without hitting F12.) Thanks for any help, I'm on a live CD
boot: grub doesn't start Posted on October 4, 2014October 6, 2014 by deshack in Ubuntu TweetWhen you want to install Ubuntu in dual boot with Windows 8, you need to take into account that you can encounter some problems. Today I'll tell you an anecdote and explain how you can fix the following problem: grub doesn't start on a Ubuntu 14.04 dual boot with Windows 8.1.The storyA week ago I installed Ubuntu 14.04, codenamed Trusty Tahr, alongside Windows 8.1 on a friend of mine's computer. I did not install the available updates upon installation, to make it faster. Everything worked well: UEFI did not cause any trouble, both Ubuntu and Windows started as expected. I then installed the Italian locale packages and postponed the updates.Today I finally found the time to update the installed packages. Once installed, I restarted the computer in order to apply and test the update. And here comes the surprise: grub didn't start, the pc booted Windows directly.Solve the problem: grub doesn't startWe have a problem, but fortunately Windows is not compromised. So, let's go and fix the problem.What you needIf grub doesn't start, we can't access Ubuntu directly. Here's what you need:a live Linux distribution either on a CD/DVD or on an USB stick;a little bit of patience.Nothing else? Exactly, that's it.First try: Boot RepairThe first thing you can do is using Boot Repair to reinstall grub with all the options you need. You can find instructions about how to install and use Boot Repair in the Ubuntu Community Help Wiki.How to solve the problemMost probably the first attempt with Boot Repair didn't solve the problem. But we are Linux users, so we can find a solution by searching in the Web and with a little bit of luck.Boot into your live Linux distro (from now on we're going to call it just "Live") and open GParted or any other partition manager it has. Look for your Ubuntu system partition and write down somewhere its file name (that in the form /dev/sdxn, in my case /dev/sda7) and its filesystem. We'll call it /dev/sda7, but keep i
