Ubuntu :: Grub Does Not Recognize Win 7
Nov 16, 2010
I have have just installed 10.10 on my Acer Aspire laptop. I connected to the Internet during installation and therefore should be right up to date. Grub2 does not show Windows 7 as a boot option. Did a bit of searching and ran sudo update-grub2 but no success. I am a newbie as far as Ubuntu is concerned. I installed 9.04 on my netbook and that worked fine. I have the added problem in having to get into Windows very shortly and I haven't a clue how to do it if grub remains broken. Windows partition still there I have not deleted it.

It worked fine for awhile, but recently my usb keyboard wont work, ONLY IN GRUB. So I cant use grub to select another boot option. This kbd does work in Ununtu and on my other XP machine. Old version of Grub, I believe. (not GRUB 2). No error messages displayed.

I have 2 internal harddrives.
I installed Vista on sdb1 and later Ubuntu on sda1.
When I boot up, I am given choice of OS's to boot into. That worked fine until I formatted sdb1 and installed Windows 7.
Now when I boot, I am given the exact same options as before, and when I select the the old "Vista" Menu item, it gives me an error that it can not find some long serial number. The number is not my drive serial number. That number is completely different.
I can still boot into Ubuntu with out a problem.
Now, in order for me to boot into windows, I have change the BIOS boot order. That is obviously not ideal.

How can I set grub2 to ask me this question?
Here is my partition configuration

============================= Boot Info Summary: ===============================
=> Windows is installed in the MBR of /dev/sda.

So I am experimenting with other linux distros.....I just installed a small partition with OpenGEU, the one still based on Ubuntu.....now it wont recognize Mint. Ubuntu Studio is next on my list, but before I invest any more work I want to make sure I can add more partitions to grub, not just the most recent linux partition...
I think that future distros of linux should have a fix for this....if you install linux it should detect every other operating system on the disk, not just windows plus the most recent linux install.
install /boot separate? I always create a / and /home partition but never separate boot. Does that make life easier?

i can't boot up my win XP after installing Ubuntu 10.10.
I decided to replace my Vista partition with Ubuntu 10.10 so i redo my partitions and split the current Vista partition to a swap and root partition and install Ubuntu 10.10
Everything went well and i got Ubuntu up and running. However, i realize that GRUB 2 didn't recognize my existing windows partition. I double-check on grub.cfg and see that the default os_prober didn't recognize my XP partition either.
After search on the internet for a while, i found many similar issue where most are fix when manually adding the entry yourself so i decided to add an entry 11_XP under /ect/grub.d/ for windows XP and confirm that the new entry are added to the update grub.cfg file before restarting
Code:
### BEGIN /etc/grub.d/11_XP ###
menuentry "Windows XP" {
set root=(hd0,5)
insmod chain
drivemap -s (hd0)
[Code].....

I have a nice spare K6 machine with a 66G drive and OS/2 Warp 4 installed on the primary partition, which is all of 2G, formatted in HPFS. Like DOS, OS/2 can only be on the primary partition. I have set up and formatted 3 additional partitions as ext2 or ext3 using qParted. GRUB is a great bootloader, but does not seem to recognize the primary partition at all, making multiboot difficult. Is there a way of getting GRUB to recognize the HPFS?

My 13 year old Pentium 3 1.3 ghz machine is finally ready to call it quits. specifically, my slave drive where all of my music is stored. I can access a very small portion of the the files on the HD, The files are still there but are not showing up. any ideas on how I could access this drive. I wanted to try to reinstall my os on the primary drive in hopes that it wouldget it working, unfortunately I've run into what's seems to be a common problem of my usb keyboard not being recognized.

I had Windows 7 ultimate installed on my netbook and installed Ubuntu 10.10 using the 'Install alongside other OS's' option which put windows onto another partition and created one for ubuntu.
Anyway I've tried reinstalling the grub but I never get a grub boot menu when I boot it up and the grub won't recognize the windows install

I have just installed Fedora 11 64bit on a new hard disk, using Intel 975BX2 motherbord, 3Gbyte RAM, 320Gbyte hard disk etc., USB mouse and keyboard. The installation went fine, but when I enter the password for the boot (I assume GRUB was installed) it fails to recognise the password. Do this three times and the boot segment ??? fails to initialise.
I recall a linux magazine i buy indicating that you have to copy and paste the password manually after installation, but i cannot recall the article date. Is this a problem - the password protection for the GRUB boot loader does not work at installation time when using the graphical interface ?. I did not use any odd characters - basic letters and numbers.

First time this has happened. I installed Fedora first (XP already installed) and then installed Ubuntu 9.10 64. Fedora doesn't show up on boot up menu. I've tried update-grub.
Before I would have just edited menu.lst, but now?? I dunno.
edit; Here's fdisk with Fedora on sda6

I have a mini tower that started life using only Windows XP, I converted it to dual boot Umbuntu 10.04 and Windows XP. So far, so good, since I was using a ps2 mouse and keyboard. My problem started when I converted to wireless keyboard and mouse.....the bios recognizes the keyboard, both operating systems recognize the keyboard and mouse....BUT!!, the grub loader recognizes neither. Now, I can get around this problem by 1. letting Umbuntu load by default or unplugging the USB connection device for the keyboard and mouse and replugging my old ps2 keyboard long enough to boot to the system that I want to use.

I recently have installed Ubuntu 10.10 Maverick Netbook Edition in my personal netbook. The thing is that I had installed Windows 7 in the hard disk drive so I decided to install Ubuntu alongside with it. After the process of installation everything was cool but I hadn't the Grub working. I then pressed the Shift button during the booting process so I got the Grub menu but it didn't show the Windows 7 partition. The Windows installation was not erased because its file system is present in Nautilus. I have tried reinstalling the Grub a thousand times but nothing changes. I have attached the results of the boot info script so you can have some info about my booting configuration.

I have dual boot (winxp) which has been working for over a year now.But for some reason recently, grub wont recognise the keyboards arrow keys. ie cant change menu selection. in fact it wont recognise keyboard at all it seems. Pressing enter wont work either. I have to wait for the timeout.
The arrows work before hand (like in bios settings) and after once ubuntu has booted. Just not in the grub menu
Its something to with the USB wireless keyboard. If i replace it for standard PS2 kybd it works.

My computer is currently dual boot: Windows 2000 on first hard drive (master) and Ubuntu 9.10 on the second hard drive (slave) using GRUB 2. Both drives are on the first IDE channel. I have a third drive with a DVD/CD drive on the second IDE channel (master and slave respectively). The only thing on this drive is my photo library, which is backed up on a server.If I were to temporarily remove the plug for the first two drives from the mother board and plug the third hard drive and DVD drive into the first IDE channel and install Windows XP on the third hard drive from the CD ROM, I would have a functioning Windows XP computer with just the hard drive and CD/DVD drive. The system would not know of the existence of the dual-boot configuration.
Now the question: Obviously, if I plug the drives back in the way they were originally, I will not have the choice on GRUB to boot into Windows XP on the third hard drive on the second IDE channel. When running from Ubuntu, can I do a GRUB update, and will it recognise the new Windows XP drive as a bootable option in the GRUB menu?I really don't want to take the chance of destroying my current dual-boot configuration (Win 2000/Ubuntu 9.10) by installing Windows XP on the third drive with the first two drives plugged in.I don't really want to take the time to experiment if there's no chance that GRUB will recognise the new Windows drive.I know. I'm a little old-fashioned. But when all my applications work fine on both platforms with the hardware

I would like to know if there is any differences on how to install and to configure GRUB 2 in the different architectures (BIOS/IBM PC-Compatibles, EFI/MacIntel and Corebbot)? Does the Ubuntu installer automatically recognize the different architectures and install the appropriate GRUB 2 package ('grub-pc', 'grub-efi' or 'grub-coreboot' according to the arch)? Or does it just install 'grub-pc'? Is the location of GRUB 2's configuration files different depending on the arch of the computer? Or are they all located in '/boot/grub/', '/etc/grub/default' and '/etc/grub.d/', no matter the arch of the computer? Are the files' structure and options to configure GRUB 2 ('/etc/grub/default' and the scripts in '/etc/grub.d/') different depending on the arch of the computer?

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

I'm just slightly confused here, but... what the? Why does installing grub-doc remove BOTH grub-pc, and grub-common? So basically it seems like by installing grub-doc, I have uninstalled grub totally (yes, it is still there as the bootloader, but i have no way of updating it now!) from my system. What's the conflict between grub-doc and grub-pc, such that grub-pc has to be removed?

I have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.

I just installed 10.4. I had a USB HDD that contained an old (8.04) version. I wanted to format the old drive. But whenI plugged it in UBUNTU won't recognize the drive. It's like there was not USB drive I know the connection works cause it works on Windows (XP Pro)with the same enclosure.

I understand that RAM capabilities is mainly based on your mobo, but lets say the mobo can handle 32gigs (Exaggerating here). I'm currently running 2 gigs on my current system, and am thinking about bumping it up to maybe 4, 5, or even 6... I know my system can handle more than 2 (which is why I'm doing this, and I'm trying to do high RAM tasking things) so how much RAM can ubuntu 11.04 64 bit OS handle, recognize, and use to potential? I've googled it plenty of times, but I'm only coming up with people saying "oh it's whatever your mobo is capable of," which is true, but I want to know if there is like a pre-determined limit that 11.04 64 bit OS will only use if installed.
Like how some 32 bit OS will only use lets say 3.0-3.5 gigs of an installed 4 gigs. I don't want to go out of my way and spend money on a few extra gigs if my system will only recognize a portion of it. I know my 64 bit will recognize whatever I'm willing to pay (which won't be too much more ) but I'm just curious.

When everything was working fine, when I inserted the usb or disc an icon would appear asking if I wanted to mount the drive. Now nothing appears. It's been like this almost a year.

I'm trying to restore my laptop through the Ubuntu 10.04 Live CD. A while ago, Windows 7 died. I've tried everything possible to make it work again to no avail. At first I gave up on recovering my files and proceeded to formatting it, but that didn't work either, although it would boot from the CD, it would get stuck. It's as if the HDD couldn't be accessed.
After trying almost every version of Windows available, I decided to give Ubuntu a shot. I have used Ubuntu before and I thought maybe I could use the Live CD to see whether I could access the HD or not and, if not, claim the warranty (I bought the computer 4 months ago). I downloaded Ubuntu 10.04 and booted from it and was able to access all my files.
I wanted to move my files to an external HDD through the USB, but I plugged it in and nothing happened, no icon appeared on the desktop or on the Computer directory. I plugged in a normal USB flash drive, and no icon appeared. The funny thing is that the USB led lit up, so I knew it was connected to the computer.
I thought maybe Ubuntu wasn't mounting the drives and that I had to do it manually, so I ran both the lsusb and fdisk -l commands on the terminal with both drives plugged in and neither of them appeared listed. I even opened the message log to see if there was some reaction when I plugged it in, but nothing worked. :S
I restarted the computer and opened the BIOS to see whether the USB drive was enabled, as I had previously disabled some options trying to restore Windows, but the external HDD was being recognized by the computer; on the boot list it showed the name and serial of the drive, so that wasn't it.
I downloaded previous versions of Ubuntu, thinking maybe it had something to do with that (although I know it shouldn't), and the same thing happened: I could access the internal HDD but the external drives weren't being recognized.
I've browsed through the forums, going over the same procedures as other people with the same problem, but nothing works for me and now that I know that my files are safe, I don't want to format it anymore before saving at least the most important ones ><
I think I have 2 options before I run out of ideas. I could use GParted or Partition Editor from the Live CD to resize the partition to make enough space to install Ubuntu on my computer (I was thinking of doing it, anyway) and then fix everything from there instead of from the Live CD (if that changes anything), but I'm afraid that the files in the partition could become corrupted or damaged, and I don't want that. The other option would be to install Ubuntu on the external HDD and boot from it, as it WOULD HAVE to recognize it.
I want to know if there is any way to solve it before resorting to the latter option, as the HDD is not mine and I don't feel right partitioning it.

I had a motherboard 'POP' and die. I replaced it, the CPU, and ram along with a new PS. Then the IDE CDROM always read 'zero' for any media placed in it, so I bought a new USB DVD/CD do-all drive (LG G0 The system was desktop Dual (sic) Boot with WinXP. The XP would boot from the GRUB, but no Ubuntu. I used >find /vmlinuz and got H0,6, right where it always was. But I could not get it to boot
So I reformatted the IDE with Winxp (all my good stuff is on a SATA drive that I left out of all this )) unplugged. The Live CD wouldn't find the IDE hard Drive XP had just installed on- same as BEFORE I reformatted it. I tried all the distros I have (Puppy through Slackware, Suse, Sabayon, etc) .
Nothing could find the IDE drive. I flashed BIOS on the new MB-no help. I put Linux on a Flash drive and booted from there- no help No Partitioner can SEE the IDE...but XP runs on the IDE C:/ just fine (ntfs for C:, with 70GB unpartitioned, waiting for Linux) I am at a loss.
As far as I know, if the BIOS sees the IDE, and XP can run on it, the IDE HD is THERE and working. Yet no Linux can see the IDE HD, XP partition, blank partition, NOTHING. even dmesg shows no IDE The boot text shows no IDE in linux, right after the BIOS lists it correctly while booting.
