I have a MacBook pro and have downloaded bootcamp Windows 7, and was trying to dual boot Ubuntu. I got it to download and start and went into the installation setup and it asked me to do something with the partitions and I was messing around and accidentally marked the Windows folder as biosgrub.   It then froze and I forced it to shutdown, but when it rebooted, it said missing operating system and I can't boot Windows anymore. I can get into system recovery and can still see the files, but it just won't boot. I could restore OS X and buy another Windows disk, but I was wondering if there was another way.

I installed Windows on my computer, followed by an installation of Ubuntu. However, now I'm unable to boot into my Windows install.  What can I do to fix this?

After making an error installing windows, I now have two entries in the Windows 7 boot loader, one of which is incorrect.  How can I remove it? I've seen some entries recommending EasyBCD, but can't it be done easily without 3rd party software?

I have a Windows 10 computer. This morning it restarted into a blue screen with error code Inaccessible boot device.  There are no recent hardware changes. Also I think it was not after a Windows update installation. At least I chose Restart to restart, and not Update and restart as usual before an update installation.  According to other posts related to this problem I tried the following:   Restart into save mode: no success, the same error displays Restart into recovery console: The system partition usually mounted as C: is available as D:   chkdsk d: /x completes without finding any error. I conclude, that the problem is not related to a hard disk failure. bootrec /fixboot completes with success.  bootrec /scanos completes with a message Number of Windows installations identified : 0. Why doesn't it find the Windows installation, even though it is available under D:\ ? sfc /verifyonly has found integrity violations, but sfc /scannow finished with the message The Windows resource protection was not able to complete the operation.  System restore to a previous restore point: After a (long) while, the task completed, but without solving the problem. Booting from the Windows Installation disk:   I tried the option Repair Windows: It was not possible to roll back to a previous restore point Update Windows keeping programs and files seems to work only when booting first into the current installation to do an upgrade. It cannot be done while booting from the installation disk (as it was the case in previous versions of Windows).     Is there anything left I could do before reinstalling Windows 10 ?  Edit: Now there is the second computer with the same problem within 2 days. This smells like an epidemy (caused by a bad Windows update ?)  This time I tried:   Restart into save mode: no success, the same error displays System restore to a previous restore point : No success, it offers to try from another restore point.   I stopped here. I just don't want do make a mistake that forces me to reinstall it.

Long story short, I installed ubuntu while I was watching netflix and feeling very lazy, and may have lost all my windows 7 files.  Quick summary:    -Windows 7 was installed on Legacy bios and I installed ubuntu on UEFI bios -ubuntu installer didn't detect any other OS on my computer and wanted to write over the disk, so I had to manually edit the partition    -Despite repeated warnings about partitioning windows in the ubuntu installer, I did this anyway, assigning 140 gigs to ubuntu and 500 to windows Now, my computer won't boot into anything but Ubuntu  -in Gparted, it still shows that I have two partitions, and windows 7 boot loader -However, I can't boot into the non-linux partition, and boot loader says I need a recovery disk.  My question is does anyone know if what I've done is fixable? I'm hoping that I can fix it using the way outlined in this thread:   Thanks for the help everyone!  Note: gparted shows:    Foudn linux image: /boot/vmlinuz - 3.13.0.30 - generic   Found linitrd image: /boot/initrd.img - 3.13.0 - 30 - generic   Found linux image: /boot/vmlinuz - 3.13.0 - 24 generic   Found  initrd image: /boot/initrd.img - 3.13.0 - 24- generic   memtest   memtest   Found windows 7 (loader) on /dev/sda1

Previously I installed Windows 7 on a Macbook Air without problems using Boot Camp Assistant and the excellent directions .  Now I am trying to install Windows 7 on a Mac mini server and I encounter error with every approach I take. I already have a bootable USB disk with Windows 7 installer.  First I tried to install Windows 7 directly booting the installer. Installer refused to continue displaying an error mentioning something about GPT drive.  Second I tried to install using Boot Camp, but it does not exist on Mac mini servers!  So I copied the Boot Camp Assistant app from Macbook Air, and selected the option "Download the Windows Support software for this mac". It was not able to find and download anything.  I thought I could handle the driver issues later, I used Boot Camp Assistant to make the 500 GB harddisk Windows installable. Then I booted into the installer, selected BOOTCAMP partition and formatted it. Installer did not continue displaying 0x80300024        error.  I run out of ideas and am rather frustrated. Are there any simple instructions on how to install Windows 7 on Mac mini server? Or how can I solve my problem and install?

It's my first time installing ubuntu. I have Windows 7 and 8 before in my laptop (Acer Aspire 4752z). After Ubuntu (12.04) installed in my laptop, the Windows boot loader didn't recognize my Ubuntu so I updated grub from a live USB.   And after grub updated, Ubuntu was booting perfectly but my Windows wasn't listed in the grub menu. So I follow someone instruction to update grub again. And after reboot, the grub menu didn't show anymore.   After searching about this problem on the net and trying to update grub again and again, I decided to delete the Ubuntu partition from live USB. And shortly after, I booted to Windows with Hiren boot and I used mbrfix. But i think it failed. Now i cant show my BIOS setup or boot from DVD or USB.   After that, the only screen i can see after booting is:  error: unknown filesystem grub rescue&gt;

I sent this to boot.repair@gmail.com, still no response thought I could get a faster solution here.  I am running Windows 7 64-bit and Ubuntu 12.04 LTS on separate partitions.  The message is sent is:  Boot-Repair URL:    Originally I was unable to access Ubuntu after a windows update (Ubuntu was installed using wubi). Rather than logging into Ubuntu from the Windows 7 Bootloader, it lead to the grub> command prompt.  No matter what I did here, it would not log me into linux.  As a result I uninstalled Ubuntu from the Add/Remove Programs application in Windows 7.  I then re-installed Ubuntu 12.04 LTS using a liveCD-USB.  This time however, I created a partition.  I then restarted and got the GRUB bootloader which loads Ubuntu 12.04 LTS with no problems, however when I select windows (listed as "Windows 7 (loader)"), it just refreshes the grub bootloader instead of loading Windows 7.  I then used the Windows 7 repair disk to run bootrec/fixmbr and bootrec/fixboot.  This led to no bootloader coming up when I started my computer.  Instead I got a blank black screen with a flashing white cursor.  I went on to do a bootrec/buildbcd and bootrec/scanos.  These did nothing to change the situation.  When I ran bootrec/scanos it said that no Windows 7 installations were present.  After this I decided to reinstall WIndows 7 only for this to do nothing to change the situation.  Afterwards I did a boot-repair in which I began to get the GRUB bootloader, which would load ubuntu 12.04 LTS, but still would not load Windows 7.  I also did a sudo update-grub which recognized Windows 7 as being installed, but still didn't fix the issue of loading Windows 7.  While running Ubuntu I have no problem accessing my WIndows 7 partition which is formatted as NTFS.  It shows all the files and folders reflecting that the re-install did take place, and it also shows all of my old applications and folders in the Windows.old folder.  I am completely stuck at this point and have no clue what I should do next.  Any help you can offer me will be greatly appreciate.  Thank You  --gap

I installed Windows 7, which ate Ubuntu's boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.   How can I get Ubuntu back?

I have dual booted Ubuntu with Windows 7. I wanted to uninstall Ubuntu. So as per an answer for one of the related questions on this site I did the following:   Deleted the Ubuntu Partition through Windows. As per the answer now I was supposed to boot Windows from USB &amp; then do "repair startup".   But Windows could not find any problem hence nothing was done. So when my laptop booted normally (i.e. from HDD) it was showing some error like GRUB:/ unknown file system. I dont remember the exact words but it was something like this. Thus I couldn't boot windows neither Ubuntu. So again I had to install Ubuntu.  But now my question is how do I remove Ubuntu so that my laptop returns to the previous state of installing Ubuntu?  UPDATE: Seems that it wasnt on this site. My mistake :P .Here is the link

I have a Mac Book (2006)    2 gb ram 2.2 GHz processor core 2 duo (intel-based processor) 80 GB hdd loaded with Windows 7 x86 only (single boot) - I've deleted the Mac X OS completely before and I don't have any Mac OS DVDs right now   So here's what I want to do:   I want to install Ubuntu 12.04.3 on my Mac as a single boot (and get rid of windows 7) How exactly can I do that?? And How can I also dual-boot Ubuntu and Windows 7 on this Mac? (in case I want to in the future)

I'm new to how Ubuntu works and installed it yesterday alongside Windows 7, but in doing so I have created a few problems. I have partitions for Windows, Ubuntu, System Recovery, and storage for all my files with the intention to access them on either OS, but I don't even see all of my drives listed on Home Folder. Not to mention that  during the Ubuntu instillation I managed to screw up any chance of booting to the Windows side of things at all. I'll fix Windows once I get my hands on a copy in a couple days, but in the mean time any suggestions for accessing my files?  If you need me to find any data about my computer to help you figure out what's wrong with it, please don't hesitate to tell me what I need to show you. Thanks

I have a problem on boot camp where when I try to click continue but I get this message. Can anyone help?     The startup disk does not have enough space to be partitioned.   You must have at least 40GB of free space available.       Possible Fixes   It could maybe be time machine since I have it enabled. But as you know High Sierra does not give you the time machine off switch in system preferences  It could also be a disk utility partition error but you can clearly see on the image below I only have 1 partition which is my main OS hard drive

I am trying to download Ubuntu to put it on my daughter's MacBook (just installed new HDD, so no operating system on it)  But from my Windows PC all I can see is the Windows Ubuntu. Can I use that, or is there a specific place I can go to get the Ubuntu download for a Mac please?

I have installed Ubuntu on my USB drive according to the instructions here   and the installation went successfully and Ubuntu was running on my mac. After I restarted the mac I couldn't be able to boot Ubuntu again from the Startup Manager, When I press (Option ⌥) key I only found the main hard drive that boots me into macOS.  How can I solve this problem and boot into the USB drive again?

Using the latest Macbook Pro with currently High Sierra 10.13.1, I was using bootcamp for a year, and I decided to get rid of the Bootcamp partition this morning. The Bootcamp utility would not let me erase this partition, so I decided to do it through Disk Utility.  I did everything I could to "erase" it, but I can't find any way to merge this 58GB partition with my primary Macintosh HD one.    In Disk Utility, if I want to erase the container Disk2, it tells me that an internal error occured... The BOOTCAMP partition is actually formatted as APFS...    $ diskutil list     How can I merge those two partitions ?  EDIT : The BOOTCAMP partition is now gone but I can't extend the primary one ...

I have an iMac 2008/2009 issue and recently the computer would not boot and I would get a flashing question mark. Ran through all the usual steps, try boot in safe mode, flash RAM,  try single user for fdisk, put in OS disk and boot from CD, etc... No dice.   Replaced the hard drive and put the OS disc in the system, press and hold option. (holding C didn't work) I can see the OS disk but when I click on it the system will act like it is going to run and then freeze. The best I got was the OS X disc that changed the screen to dark grey and told be the system had to restart.  Purchased a usb mount for an external hard drive. Was able to mount the old hard drive to a laptop and run disk utility. Everything checked out.  At this point I am pretty sure it isn't the hard drive.   Any other hard ware items this can point too? My iMAC can also "see" the hard drive (and the recovery partition) when connected via the USB and I hold "option" on start up. But it crashes when trying to boot from either.  I am going to take out and re-install the RAM for giggles but I am not sure what else to do.   Ideas are welcome.
