Debian Installation :: Can't Boot Back To Windows
Nov 20, 2015
I installed Debian 5 hours ago, and I am fighting with it since then. I'll pass on the tons of issues I am encountering (wrong desktop environment (I asked for debian's, I got Gnome), shitload of various errors when doing basic things, resolution of a minitel).
The biggest issue I am having is that Grub is not listing Windows and I can't boot into it. I've tried os-prober and update-grub, the boot info script detects Windows 7 (it's windows 10 but, whatever), I've tried to boot into a windows repair USB stick and fix the mbr and boot through the cmd (which both returned success). I am currently trying to create boot-repair USB stick, but I keep getting errors about file systems not handling symbolic links...
How can I repair Windows boot (which seems to have been messed up by Debian's setup)..
Also, I am quite used to linux and unix systems, as I am dev and use Mac OS at work and used Ubuntu/Fedora for years, and I never had such a bad and messy experience with any of those OS...
Here is the boot-info generated with Boot-Repair-Disk [URL] .....

I wanted to go back to try Ubuntu again. I used to use it and I wanted to try it again. So I make a partition on my external hard drive to put Ubuntu in. I tried WUBI but that wouldn't work, so I downloaded it and burned it to a disc. I boot into the disc and install Ubuntu NOT on the partition I made. (It wouldn't install there). So it made it's own partition on my External Hard Drive. It installs, my computer restarts and the disc comes out.
My computer is booting up when a command line type screen comes up saying GRUB recovery or something along the lines. I can't do anything or get past it. So I restart my computer with the Ubuntu disc in, and it brings me back to the install menu like it never did anything. I looked in the Disc Utility and saw everything is still in it's place, so nothing happened. I really don't want to be stuck in this Try Ubuntu thing. I can give you all the information I can.

I just installed Ubuntu 11.04 via USB drive. I have 3 disks on my system. Two are 1TB drives and are actual real drives, labeled sda and sdb. sda is where I installed Ubuntu (on its own drive). I also made sure that GRUB was assigned to sda during setup.The 3rd drive isn't really a physical drive, it's a stripped RAID. My BIOS has Intel raid support, and I have 2 500GB drives that form one 1TB drive, and that's the one that Windows 7 is installed on. How do I setup GRUB to allow me to boot back into Windows 7?

just recently, while attempting to boot to windows 7, i happened to select the wrong boot option by mistake, that is the windows 7 recovery (something like that, cant remember it specifically, but the word 'recovery' is there). the option has been there eversince i installed ubuntu 11.04 on my system, of which i cant find the answer as to why it existed there. so once i selected it (which was by mistake), it took me into some recovery process which i abandoned as quickly. it restarted and the windows 7 option was no longer there. the windows 7 recovery option, however, is still there. How to get my windows 7 boot option back?

Whenever I load Ubuntu on a machine with other OS(s) loaded it always recognizes and adds an entry in the bootloader menu. Not this time. Well kind of. After the install my windows boot option was in the menu, but after an update it is no more. I see the different Linux images... but no Windows boot option. Can someone tell me how to add my windows XP boot option back to the bootloader? I have XP on the the on the 5th partition and Ubuntu on the 6th...

I'm not sure if this is the right spot for this pst or not, first on this forum. I just removed Fedora Core 4 from my system and installed Debian Sarge with the 2.6 kernel. I'm a newbie. The install seemed to go fine, after it was done I actually logged in and looked around some. I then restarted to check to make sure that my boot process went ok and I could still get to windows. Worked fine. Then I tried to boot back into Debian. It hung. I rebooted and tried again. Hung again in the same spot.

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 had a fresh Windows 7 install on for a few days before taking the plunge with Ubuntu 10.04. It's great except I want to go back to Windows 7 to reformat by iPod with the Windows HD structure. The problem I have is that when I restart and I am presented with the options of whether I want Ubuntu or the safe mode for Ubuntu or Windows 7 to boot I can't use the arrow keys on my keyboard to scroll down to select Windows. The arrow keys don't work.
The keyboard works fine with the computer. And the Esc, F12 keys etc work to access the bios but not to scroll down and select my boot choice. The keyboard is a silver mac one with the keypad [URL] I've tried searching for the right drivers for the keyboard in case that's it and I've searched these forums and google to no joy.

I've finished the installation of Debian Squeeze using Installer loader from Windows. But the Installer menu is still appear on Windows Boot Manager.
I've try to uninstall the "Installer Loader" from Windows and I got an error message about BCDEDIT (if I'm not wrong), during uninstallation process.
I ignore it, and continue the uninstallation process until complete. But, After I reboot my computer, the Installer menu is still appear on Windows Boot Manager.
I'm using Windows Vista Business SP2.

So I needed to remove linux from a dual boot, single drive setup I had going. Without thinking I was in Windows XP and formatted the linux partition I had created. After trying to reboot the computer I receive a Grub 1.5 Error 17 rightfully so.
I am having a hard time finding a solution... All I need to do is get the machine back to being able to boot into Windows without any prompts.

I have an Acer Aspire 5810T which came with Windows Vista. I prefer Ubuntu but I need some windows applications so I dual-booted Vista and 9.10.
There was a few minor problems with the Vista side but I didn't use it enough to care. A few weeks ago Vista would not open some programs and others would shut down automaticly and some would open but not connect to the internet like they should. This happened on my previous laptop and when I used the system recovery discs to restore the computer all those issues were gone.
I used the recover discs to restore everything to its original factory settings, it said everything was successful so I restarted. My computer got to the grub menu but when I chose Windows Vista as my operating system it goes black for half a second then returns to the grub menu.
I can get into Ubuntu fine, and I can see the Vista files when I mount the drive to Ubuntu. When I look at the files everything is the way it should be if I had restored it but I can't boot it..

First, let me start off by saying that for the past 5-6 months I've been using Linux stand-alone without Windows at all. Recently though, I got netflix and found that there is no support for Linux distros. So, begrudgingly, I installed a small Windows Partition on my computer. So here's the problem: I can't boot back into Ubuntu. Whenever I turn on my computer, it automatically boots up into Windows 7. I know my Ubuntu partition is still there, because when I boot from my live disc I can see it. Is there a way I can fix this using Windows and/or a live disc?

I installed Ubuntu, with a dual boot functionality and worked great. I was recommended Backtrack 4 and I installed it in the system. Now, I try to use the dual boot with Backtrack, Ubuntu and Windows 7 and only Backtrack works. I tried the restore disks that I created when I got the laptop, but the problem persists. s there a way to delete this Backtrack from the system and go back to Windows 7?

I'll start off with stating my problem and summarize how I got to it.
I installed Windows 10 on an SSD. I installed Debian 8.2 after it. The SSD was/is a GPT disk. I installed both installations from a UEFI booted device (DVD for Windows, and USB drive with Live CD for Debian).
I tested it after each installation making sure I could boot via UEFI into Windows, then Debian, then Windows, to make sure nothing broke.
I rebooted the machine. Suddenly, no more UEFI. Nothing. I didn't change any BIOS/UEFI setup menu settings. Not even my USB drive with Live CD will boot through UEFI anymore. Even when nothing else is plugged into the system.
My situation is actually a bit more complicated than that, but I think that will suffice for now. I can still boot into the Live CD on the USB drive, just in Legacy mode only. I mounted the EFI partition on /mnt/boot after I mounted the file system for Debian on /mnt. It is identical, as far as I can tell, to as it was before when it was working.
My motherboard has CSM and Secure Boot, both have been set up how they need to be to boot UEFI into Debian. Tinkering with them further after things broke did not fix it. I tried all variations of options/settings.
The GRUB Reinstall guide says to be in EFI mode before starting it, so I can't do that.
My motherboard is an ASUS X99 Deluxe, and I've heard ASUS has special "features" (read: bugs) that come with their boards. Searching hasn't brought up any other people with this issue. I believe the firmware is updated to it's most current one.
I've tried dd-ing my backup of my old system, from before trying to migrate to a Dual Boot system, to the SSD (after backing up the dual boot setup with dd -> <name>.img via the Live CD USB). However, that won't boot either as it is a UEFI install as well.
The layout of my EFI partition is as such:
/boot/EFI/Boot/bootx64.efi
/boot/EFI/Microsoft/<Microsoft-naming>.efi
/boot/EFI/debian/grubx64.efi
I've heard that the standards on how that's supposed to be set up isn't a standard. However, since it worked booting into the OS' the first time, I don't see how that could be the issue (a bad hierarchy layout leading to the UEFI not being able to see the OS installs).
I've seen that I can boot to an EFI shell (called Shell.efi, apparently) via an option in my UEFI BIOS setup menu on my motherboard. Is that an option here to somehow bypass this strange issue?
All I can think to try is burn it all and start over. But not knowing what caused it means I could just make it happen again. Plus, I can't boot into UEFI install media, so I can't install UEFI boot OS'. :/

I installed lenny and now my windows 7 won't boot. When I select it in Grub the machine just restarts the bios after a few seconds of black screen. The machine I'm using is a very vanilla intel p4.
I'll paste my /boot/grub/menu.lst below. All of the drive options look correct. I properly shutdown Windows 7 before installing lenny. I'm sure I can reinstall the mbr and get my windows back, but I would like to dual boot with grub.

I've recently bought a new computer and installed Windows 7 on it, but left 100GB of space on a separate partition so I could put Debian next to it in dual boot. I have the new Intel i7 950 processor and I run Windows 7 Proffesional 64 bit, so I assumed I had to pick the ia64 debian image. However the CD I burned from the ia64 image didn't boot. (a black screen started and an underscore kept flashing, but nothing else happened)[URL]
I've managed to install i386 Debian on a older intel pentium 4 computer before and that worked fine. I believe I used another application to burn the CD then. This time I've burned the CD with the default Windows CD burn application. I can try burn more CD's but I don't have much left so I want to make sure this is the problem before attempting again. (the burned files on the ia64 CD look exactly the same as the files on the i386 CD, when browsing through the cd files in windows) "If your PC has a 64-bit AMD or Intel processor, you will most likely need the "amd64" images (though "i386" is also fine), the "ia64" images will not work."This seems a bit strange, they recommend me to use the amd64 image if you have a "64-bit AMD or intel processor". I dunno if this is a typo, but it seems weird to me that the AMD-64 Debian version would also work on my Intel machine

I recently installed Debian 7 on a dual boot with Windows Vista. Thus, when I boot the computer, I am prompted by a GRUB screen to select Windows Vista loader, Debian, and Debian (recovery mode). I would like to upgrade Windows Vista to Windows 7. Will this cause an issue with GRUB? Will a Windows 7 loader be added to the list or will a Windows 7 loader replace the Windows Vista loader? Will there have to be a setting change within Debian? Within Windows?

I have a Dell laptop (inspiron 1150) which was dual booting Windows XP and Ubuntu 9.04. I have successfully installed Debian Jessie Standard over the Ubuntu. I pre-partitioned using gparted-live to make a separate single partition for the Debian install. Guided partitioning was then carried out by the installer producing separate /, /home, and swap partitions. After installation, the grub menu shows an entry for Debian and Windows XP. I can boot Debian, but not Windows XP. The symptoms are the same as reported in other forums: A terminal is displayed, vanishes and the system reboots defaulting to the Debian boot.
The grub.cfg file for the Jessie system has an other-os entry:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" {
set root=(hostdisk//dev/sda, msdos2)
search --no-floppy --fs-uuid --set=root cc0ce0ab0ce091ae
drivemap -s (hd0) ${root}
chainloader +1
}
The original Windows entry for the Ubuntu install was:
Code: Select allmenuentry "Microsoft Windows XP Home Edition (on /dev/sda2)" {
insmod ntfs
set root=(hd0,2)
search --no-floppy --fs-uuid --set cc0ce0ab0ce091ae
drivemap -s (hd0) ${root}
chainloader +1
}
The partitions produced by partman look OK (during the pre-partitioning I did not touch sda1, sda2, or sda3):
Code: Select all~ # fdisk -l
Disk /dev/sda: 37.3 GiB, 40007761920 bytes, 78140160 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code] .....
Partition table entries are not in disk order.
The os-prober found XP:
Code: Select all~ # os-prober
/dev/sda2:Microsoft Windows XP Home Edition:Windows:chain
So it seems that everything is in place, but there are perhaps important differences in the grub.cfg files. Are the two "set root" commands equivalent for example?

I have Windows 10 and Deb 8 dual boot, and I need to re-install Windows but want to avoid (or at least plan for) losing Grub/Linux boot.
Last time I re-installed Windows after Linux I ended up having to re-install Linux again afterwards as well, because I couldn't recover it (seemingly due to complications from encryption). So this time I'm wanting to plan and avoid that.
CURRENT DISK PARTITIONS:
Code: Select allsda1 | 550M | EFI System
sda2 | 128M | Microsoft reserved
sda3 | 175.8G | Microsoft basic data
sda4 | 286M | Linux filesystem (Boot)
sda5 | 28.2G | Linux filesystem (Root)
sda6 | 91.3G | Linux filesystem (Home)
sda7 | 1.9G | Linux swap
[Code] ....
As there is a "Microsoft Reserved" partition and a separate Microsoft directory within the EFI partition, if I just go ahead and reinstall Windows will it install it's boot loader/image to one of it's own partitions? And NOT affect anything else like Grub and other Linux things?
Logic tells me yes, but there seems to be many issues on the internet about installing Windows after Linux.
My primary concern is whatever happens with Windows or anything to do with dual loading etc, is that Linux will still just boot, or I can get it working again without much hassle.
Why is there a reserved Microsoft partition AND a Microsoft directory in the EFI partition? Which one boots Windows?
Why is there a separate Linux Boot partition AND a Linux directory in the EFI partition? Which one boots Linux? Where is Grub invoked from, is one redundant, etc?
How these work. It is possible I've set them up wrong, or with redundant partitions, but both systems have been booting ok for months.

I've been using Debian for a few years but always on dedicated boxes and/or VMs.
Finally decided to dual boot Debian and Windows on my main Desktop PC.
Installed as I normally would using, however this time using a seperate drive (one for the existing Windows 10 install and the other for Debian), Debian install detects that windows has an EFI partition and sticks an entry in there, which is fair enough, and everything working fine. Then I spent some time configuring all my software and set it all up just the way I like it. I've rebooted Debian a few times to check it's working correctly and it is.
The issue arrives when I reboot and load into Windows 10. It boots fine.
However after a further reboot GRUB no longer loads... and the machine just boots directly into Windows 10.
After doing some further digging into my EFI partition (and reinstalling various times) it would appear that after a reboot Windows 10 deletes the entry GRUB creates in my EFI partition after EVERY reboot.
Done some googling and most people advise turning off 'fast boot' in Windows as it locks certain partitions to facilitate the machine going into hibernation, only to find that it's always been turned off on my machine (I recall due to a driver issue with my graphics card this had to be turned off when I installed Windows 10).
I've found this article on the Ubuntu forums : [URL] .... however I've tried their steps and windows is still doing a hostile takeover of my EFI partion after a reboot!
Any way to stop Windows 10 from interfering with my EFI files after a reboot? (without doing the obvious thing and kill Windows off).

I have used dual boot systems using various versions of windows and Debian for many years and have encountered no problems. However, I have a problem with installing Debian on a EeePC (ASUS PC1201) which uses Winows 7. I can not even get started because I can not understand the information that I have on my hard drive partitions. Windows 7 says that I have the following :
Local Disk(C:) 78.1 GB free of 99.9GB
Local Disk(D:) 49.8 GB free of 83.8.GB
NewVolume(G:) 948 KB of 0.99 GB
Local Disk(F:) 37.9 GB free of 38..0 GB
(Originally the ASUS only had two partitions C: and D: I used Gparted to genetate F: and G:)
gparted-live-0.7.1.5 says that I have the following :-
/dev/sda1 ntfs 992.5 KB
/devf/sda2 ntfs 100.00 GB with 66.09GB unused
/dev/sda3 ntfs 132.88GB with 129.88 GB unused
unallocated 1.00 GB
Debian Squeeze (the net install version) will not install. G was the result of trying to provide some swap space. How do I prepare the hard drive so that Squeeze it will install on F: ?

I hope everyone is doing great. I recently installed Ubuntu on my laptop which came with Windows 7 preloaded. How I did it is that I created a new parition for Ubuntu on the same harddisk which had windows installed on a separate parition and installed Ubuntu on the new parition and made it the primary partition. The windows is still lying on its own partition.how to get windows working as well without loosing the Ubuntu installation.

I was able to install Lucid Lynx 64-bit. I selected manual partitioning which I completed without complication.
I encountered several problems after installation:
I could not use my Radeon HD 5870 graphics card. Whenever I enabled it in the BIOS, the monitor would go to "sleep." When it was disabled and the onboard 4200 graphics card was used, everything was normal. Of course, this meant that I could not enjoy my PC gaming.
Next, I could not connect to the internet.
I searched for solutions and found one [here]. After I performed this procedure, I activated the ATI proprietary driver. I also had internet! Everything seemed great. I was about to enjoy the fruits of my labor.
When I rebooted and went to Windows to make sure everything was good on that end, I got the...wait for it...waaait for it...blue screen of death.
That's where I'm at. I'm extremely hesitant to do anything else at this point for fear of not being able to use Windows altogether (I need it for school). However, during the school break, I plan to re-format the HD because I don't see any possible solution to the BSOD. Using the Windows recovery disk availed nothing whatsoever.
Furthermore, since I don't have an actual Windows CD, and my recovery disk is not doing jack, that means I will be buying a Windows 7 Home Premium disc for $175. I wasn't expecting that when I installed Ubuntu. =(
I guess what I need to know is whether I can re-format my HD to the way it was pre-Ubuntu. That means, will I be able to delete the Ubuntu partitions?
Next, is there somewhere where the Ubuntu gurus go to learn all "sudo" codes? I know there are quite a few books out there on Ubuntu and Linux, but where does everyone get their knowledge? With Windows, you can go to the website tutorial or Microsoft itself. The only vast field of knowledge I've seen with Ubuntu is this forum and perhaps Linux forum, in addition to the books. I guess that's relatively equivalent, but I don't know, I guess I'm just disconcerted because I find myself plugging in codes which I am not familiar with.

I installed ubuntu for the first time, but then I used to get two boot options, "ubuntu" or "windows". So I loaded up windows and after googling a few things, managed to set ubuntu as the default option by going to system settings in windows and changing the boot options.
I am totally regretting this now, but I set the time limit to zero (ie load ubuntu without prompt) and now I can't get windows back? I have installed startup manager but the windows option on there "windows loader" does not work and does not bring it back (the screen stays blank until I have to restart).
