My computer started rebooting when ever it would come up to the windows screen or otherwise would just never load. So I reinstalled windows. Three days later I boot it up and it says Reboot and select proper boot device. So I checked the bios and it has the hdd as the first boot option. When I restarted it came up with the option for safe mode or normal, either one I chose it would begin loading and than reboot to give same message. I reinstalled windows and it ran fine for three days, after I booted it up a second time windows ran slow, so I restarted and again it's having the same issue with it saying Reboot and select proper boot device.  OS: windows 7 home ultimate. Ram: 3 gb Hdd: sata 500gb Processor: pentium core duo 2.0 ghz

My computer no longer boots Windows or the installed operating system. Instead, I may get this error:  PXE-E61: Media test failure, check cable -or- Check cable connection!  PXE-M0F: Exiting PXE ROM.   and/or one of the following messages or similar:  Operating System not found  No boot device available- No bootable devices--strike F1 to retry boot, F2 for setup utility  No bootable device -- insert boot disk and press any key  No Boot Device Found. Press any key to reboot the machine  Default Boot Device Missing or Boot Failed  Reboot and Select proper Boot device or Insert Boot Media in selected Boot device   What does this mean and what can I do?     This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

Basically, I want to get a new PC, but I have so many software/games installed on my current hard drive, that I don't want to waste the time to re-install/re-configure. Would it work if I just take out my current hard drive, and stick it into a new PC? the motherboard/video card etc are all different, would the new PC boot up and work flawlessly?  The operating system is Windows 7.

I have two systems installed previously Windows 7 and Ubuntu. I was trying to reinstall Ubuntu and format the Ubuntu OS partition using a tool in Windows 7.   When I have Ubuntu ready on a USB stick and restart my laptop, it prompts me with the GRUB rescue screen. If I boot from USB to install Ubuntu, it just hangs.   Anyway, I messed up everything. So my question is how can I boot Windows 7 now?

I am upgrading my PC, but I'm sticking to my old HDD and gfx card. I would like to avoid reinstalling Win 8. Is this possible? Or, at least, is it possible to use Windows 8's refresh pc option?  UPDATE  It worked like a charm. Windows acted as if it was the first boot and displayed the "Getting devices ready %  " progress bar. I am not sure if this proves you can do it in every scenario, but my new gear is relatively modern (some gigabyte board with two PCIe 3.0 slots and USB 3.0 support + i5), so I guess we can agree the reinstall is unnecessary in most cases.

I recently got a computer from school. It came with Windows 8.1 installed. I then installed another copy of Windows 8.1 (so it would use the built-in Windows Pro license) and upgraded it to Windows 10. I then installed Ubuntu alongside both Windows 8 and 10. Note that I made a separate 255MB ext2 partition for /boot. Now, when I boot the computer, I first see a GRUB prompt (I already un-hid the grub prompt 'cuz I like it that way) with Windows 8 and Ubuntu options. However, there is no Windows 10 option. If I select Ubuntu, the computer boots into Ubuntu. However, if I select the Windows 8 option, I then get sent to the Windows bootloader, where it then gives me options to boot either Windows 8 or Windows 10. (However, by this point, the computer has already loaded the kernel and all. Apparently Microsoft misunderstood the concept of a bootloader and decided that that meant &quot;boot practically the entire system before actually showing the bootloader&quot;. Typical Microsoft.) How can I disable the Windows bootloader and add a Windows 10 option to GRUB? EDIT: Someone has answered telling me to disable the Windows bootloader. However, I still do not know how to add Windows to the GRUB OS list. Can anyone help with this? EDIT 2: After removing Windows 10 from the Windows bootloader with EasyBCD, it seemed that, after a few reboots, it would continually unhide itself and Windows 10 would reappear. However, I then later deleted Windows 10 from the list of OSes in msconfig, and it seems to have stayed deleted. However, I STILL have not managed to get Windows 10 to appear in GRUB. It's as if GRUB simply doesn't detect it. Also, I'll put this in the question so that people see it - I have tried using boot-repair, however, it has NOT helped any.

I disabled all services and startup applications and now the computer won't let me log in. It will get me to the initial startup screen, but it won't connect to the Internet. Then when I click or press a key to log in, the password box never appears.   How to go back to normal boot? Shift+Restart or F8 to get into safe mode doesn't work. Restoring to a system restore point resulted in an error. Even Resetting Windows didn't work.

I installed windows 10 on my laptop in UEFI mode with HDD GPT disk format, then I installed Ubuntu 16.04LTS on another partition. So I have Ubuntu dualboot with Windows 10 now.  I also installed rEFInd (it's like GUI for you to choose between different OSs) because I don't wanna use Grub2 as the default bootloader. Now I want to have Windows 7 too, but when I boot from the USB stick, an error screen showed up saying something like  the windows boot manager is having problems due to a recent hardware change   My system is still working fine so I don't know if the problem came from my system or if the setup I want is impossible.

My computer is a Sony Vaio Notebook. I used Ubuntu and Win 8 with dualboot but windows somehow managed to remove the menu to choose the OS at startup. I think the BIOS is UEFI. Secure boot was disabled already and Boot Repair somehow fails.  How can I fix this?

I’ve had a laptop fail (CPU failure according to the blinking LED) and was wondering what steps I could take to transfer its hard drive to a new machine and have it boot. It currently has Windows 10 installed (upgraded from Windows 8.1, Windows 8 before that, and originally Windows 7).  I’ll probably start by taking a backup image of the disk. The replacement laptop hasn’t arrived as yet, it’s of a similar vintage. The old machine was a HP ProBook (don't recall the model off the top of my head), and the replacement a Dell Latitude 6420.  I of course want to avoid having to reinstall and reconfigure all the applications on the drive.

Now Windows 8 supports the UEFI bootloader and I have read that its different from the BIOS, but it's unclear to me after many searches on the Google.  Some points in mind are below:-   As we all know, BIOS is an important part of accessing boot options. So UEFI will do that now? How?   How would I know that I'm booting with UEFI not with BIOS?  So what is the real difference in the "boot with BIOS" and "boot with UEFI"?

I was not able to boot in safe mode on my Windows 7 PC, so I went into boot manager and checked off boot into safe mode to see if that would fix the issue. Unfortunately it did not, and now my PC seems only to be able to keep trying to boot into safe-mode. Is there a way to set it back to regular normal boot from outside of Windows?

After purchasing a Lenovo Ideapad Flex 2 14, I tried to upgrade it and replaced the HDD with an SSD from my older laptop. After putting in the SSD, I encountered a numerous amount of problems.  First, the Windows installation program didn't see the SSD, even the Diskpart utility didn't see it, so I decided to install Ubuntu instead, which was installed successfully. Everything was fine, but after messing around with the BIOS, the laptop wouldn't load the OS unless I first went into BIOS and exited it.  Windows still never saw the SSD, even after I installed Ubuntu on it and then tried to install Windows again. What could be the problem? Also, the HDD that came with this laptop works just fine, and the SSD works in another laptop just fine, too. The SSD is Intel 335 series 240GB. I'm gonna try to install Windows 7 a little later and see if that will work, but other than that I've already wasted an entire day trying to figure it out.

I use both Ubuntu and Windows XP. One thing that catches my attention for a long time is the high need for reboots in Windows. Most of the time when I install a program, Windows requests to reboot system. This happens considerably more frequently than Linux.  Why is it so?  Thanks!

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?

I dont know whether I can ask this question here or not. Please consider this if it not a proper place.  Here is my problem, I was using Windows XP previously and I changed it with Windows 8. After installation of Windows 8 when I booted it up, I found my HDD behavior changed. Sometimes it is running and sometimes it is not.  My system specification is :  Intel Motherboard (945 Express Chipset) Processor (Core 2 duo) RAM (2 GB) HDD(500 GB)   When I open my HDD for getting the cause of problem (I open that casing and check head  and disk). I did not find any hardware visible problem. Just it is stop rotating, before it can boot OS.  Can someone help me to fix this problem or recover data in this case.  NOTE : Warranty period expired, and I have my 5 projects in that and some important documents.
