Ubuntu :: Windows 7 Doesn't Show Up In GRUB2?
Apr 9, 2011
So, as the title says Windows 7 doesn't show up in GRUB2's selection menu, but it does show my Windows XP professional option that I had before Linux and then reinstalled. After searching very long for the problem in Linux and GRUB2 I decided to boot into XP, witch gave me the option for Windows 7 or older versions of Windows -> so I eventually can boot to it! So here is the real question: How can I make an entry for Windows 7 and for Windows XP? This is because I'd like to use a theme for GRUB and it would be to stupid to make GRUB look nice if I then come to a stupid screen of the Windows loader!

I recently installed Ubuntu 9.10 onto my second hard drive, and now I can't boot into Vista (installed on hard drive #1). Grub2 just doesn't seem to be recognizing that there is a Windows Vista installation on the first hard drive.
I followed this guide (with Fabien's changes) because it seemed like they were having the exact same problem. But after rebooting, Vista is still not showing in the GRUB menu. In fact, the GRUB menu doesn't even show up unless I press Shift because it thinks that Ubuntu is the only OS installed on my computer.
My results with boot_info_script:
Code:
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=e94a058d-1d19-4a98-924b-1a5fce405bdd)/boot/grub.
=> Windows is installed in the MBR of /dev/sdb sda1:
[Code]....
When I was installing Ubuntu to HD2 (the 500gb one), I got a peculiar message saying that Windows was installed on it. There wasn't anything on HD2 though, because Windows Vista was most definitely installed on HD1.
However, if I chose to overwrite HD1 with Ubuntu, the message wouldn't come up. It seemed like the installer was confused as to which hard drive actually held my Windows Vista install.

i wiped my entire hard drive that had xp as its only OS. I freshly installed a Windows 7 ultimate and everything went perfectly. I then decided to install 10.4. I split the partitions correctly (i had experience doing this already with my laptop, which has xp/10.4). Ubuntu 10.4 install went flawlessly, except for one thing. Now when i boot up the pc, it goes straight into 10.4. I have tried holding shift during the start up to force the boot menu, and it just shows the Ubuntu 10.4 OS as choices. Any clue what i could do to make Win7 appear in the boot menu?

I'm relatively new to Ubuntu, I've installed it in Virtual Box and through Wubi on other computers but this was the first time that I've done a live install on my production computer. I had problems from the get go, I was using a Live CD of 10.04 (64 bit AMD) to install it and when it got to the part about choosing a partition no drives would show up at all. Eventually after some searching around, I discovered that Using an Alternate install CD would work. I did that, installing Ubuntu into one of the free partitions I had set up prior to this. Eventually my system turned on but the monitor went to sleep so I had to hit E on the grubmenu and change something to nomodeset (or something like that) so that I could see the screen. I installed Compiz and it was all good from there.
Except for One issue, I cannot boot Into windows at all, it doesn't show up on the bootloader even though the partition shows up in Gparted. I've tried updating Grub2 with no results, here are the results of Sudo fdisk -l
Disk /dev/sda: 400.1 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders

GRUB2 does not show Windows-XP Pro in the menu anymore.
Probably already posted before; however each case usually is somehow different. I use Ubuntu only occasionally to learn how it works.
After the latest update using Update Manager, quite a few packages were installed without any problem. However GRUB2 does not show the Windows-XP(Prof) partition in the menu anymore. Now I can't boot Windows because I can't select what is not shown.
1. This what I get with command "sudo fdisk -l" (in the present situation)
georges@PC1:~$ sudo fdisk -l
[sudo] password for georges:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code]....
It is already the second time that GRUB2 changes the menu items as it pleases, messing up the bootmenu. How can I repair the bootmenu in order to be able to boot Windows-XP, as before the updates ?
The current Ubuntu version is now 10.4 LTS The current GRUB version is "GNU GRUB version 1.98 Ubuntu10"

I've just installed the 64 bit edition of 9.10 on my workstation. My raid drivers worked without any custom installation, which is very impressive! I am however having a problem installing grub2. I boot to the live CD, run the install process, resize and partition my free space as an ext4 primary partition with mount point /. Everything installs except grub, so I'm always booting in to windows.This seems to be a bit off as I've never had this occur with dual booting before.

I have a new netbook - "Eee PC 1005PE-PU27-BK" and installed Ubuntu Netbook Remix 10.04, Kernel Linux 2.6.32-24-generic. I love Ubuntu, but I also want to be able to access Windows 7 if I can. I've read some on GRUB, but the menu on startup isn't showing my Windows 7 instance. I've tried reinstalling GRUB, but when I run sudo update-grub, I still get this:
Code:
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.32-24-generic
Found initrd image: /boot/initrd.img-2.6.32-24-generic

Found initrd image: /boot/initrd.img-2.6.32-21-generic
Found memtest86+ image: /boot/memtest86+.bin
done
I know that Windows 7 is still on the system, I just can't access it.

I want to auto mount my ntfs partition using pysdm. However, it does not see it. When I do an fdisk -l it shows up. I can access the partition through my home folder... it just doesn't show up in pysdm. I have already tried to reinstall the program.

i just installed Ubuntu from an ISO about a year old and of course i updated it to the latest version and when i get that screen at startup where i have a choice of which version to load i get something like this: My current version, memtest, an old installation of Ubuntu and some really old versions. The problem is i also have Windows7 and Vista installed(vista really needs to go) but i don't have either of them as a choice in the bootloader. How do i get it back? Also before the update i had it on the list.

I just reinstalled Ubuntu 10.04 (I was running it wubi but various issues prompted me to install it in a separate partition) and now windows isn't an option in the GRUB. I have windows Vista on /dev/sda2 and I can see it on GParted.
I tried looking through some of the other posts, but I think that I need some direct help with this one. I have tried update-grub and nothing changed.
I don't use Windows often, but it is nice to have the option.
All this is running on a Toshiba Saellite A215

I'm on Windows 7 64bit and Ubuntu 11.04 64bit.Windows is on a net book with not so much hard drive space so I want to keep all my music and movies on my hard drive of my Ubuntu desktop. When I try to find my Ubuntu machine I get nothing though..No matter what though, Win7 simply will not see it on the network. Not even when I run "\ipadress"..If anything is there away to delete everything related to Samba and start over?

I also am having this problem so any help would be appreciated.
Personally, I don't know if I have anything set up correctly. That would be something I need guidance on if anyone can offer some.

Anyway since I upgraded to Ubuntu 10.10 when I right-click on something and there is another menu in that menu, it doesn't show up for the first time!
for example if I want to create a an "Empty File", I'll right-click on desktop and when I want to go to "Create Document" menu, it doesn't show up! so I must click somewhere else and try again so for the second time it works!!

I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.

Daily updated Debian Testing Because Debian is the only operating system on this laptop and I keep at least two working kernels, I would like to hide Grub2's menu unless I press a key (like one could do with Grub). I can hide the menu if the line GRUB_TIMEOUT=0 is in /etc/default/grub but it doesn't appear after pressing SHIFT, which is a threat if the system cannot boot the selected kernel. Right now, the timeout is set to one second. I've read Grub2's documentation and [URL] and tried various combinations, but I haven't been able to make this work.

I have installed Lucid Lynx more than a dozen times in the past thirty hours and I've almost got it working with RAID. The current problem is with /dev/md0 not existing when grub2 tries to access it. When I boot from the alternate CD in rescue mode, Ubuntu sees /dev/md0 as a software RAID array and I can access the files accordingly. When I boot from the grub2 bootloader, it sits for a while before spitting out "Gave up waiting for root device" and tossing me into the initramfs shell where I can see that /dev/md0 doesn't (yet) exist. What can I change within grub2's configuration to inspire it to start /dev/md0 before trying to mount it?

I have Ubuntu 9.10, PuppyLinux431 and Windows XP on a Toshiba laptop. I like Ubuntu, but the speed of PuppyLinux is addictive, so that was my default boot until I upgraded Ubuntu which included an upgrade to Grub2.
My problem: Grub2 doesn't recognise PuppyLinux. Using information from [url] I have made an executable file named 07_Puppy in /etc/grub.d and did update-grub from root. Still no luck. I can boot PuppyLinux from the grub command line using the following commands:
Just before grub displays the boot menu, I think I see a very brief message about a syntax error, but it's gone before I can read it.
Here is the contents of my grub.cfg:
