Windows 10 cant boot after installing Solus os

Question

I recently installed windows 10 using the free upgrade and decided to get the new solus os. It was my first time installing an os and I followed the instructions provided.

Now, I cannot boot windows at all, the windows boot manager option is no longer showing. And when I try to access the Windows folder through solus. I get the unable to access "windows8_os" and something about the ntfs partition being in an unsafe state. I've searched everywhere for a solution but haven't found one. Can any one please help... Its urgent

Answer 1

Try this only if you know you're using MBR.

1. Use your recovery disk or if you don't have one, get an installation disk.
2. Restart your computer and follow the instructions that appear on the screen. Go to troubleshooting and use console to type bootsect /nt60 drive_letter: /mbr, where "drive_letter" is the drive you have Windows installed on.
3. Restart your computer.

It should automatically boot into Windows. This is the first thing you should try, there are other solutions but this should fix it. I had a similar problem yesterday and this command fixed it (although it depends on your drive). Hopefully it'll fix yours as well.

And remember to backup regularly. I've learned this the hard way. Although in your case you haven't really lost yours, it's just inaccessible.

Repair the Windows 10 bootloader

1. Just before the blue Windows logo appearance press Ctrl + Alt + Del. Your device will restart automatically.

   

2. The same as in step 1, before the blue Windows logo appearance press Ctrl + Alt + Del once more.

3. Now, the computer will reboot again. This time let the machine restart without doing anything else.

4. The Preparing automatic repair, Diagnose and Attempting Repairs alerts should be displayed.

5. Click Advanced options.

6. Click Troubleshoot.

7. If you don't see the Startup Settings option, click Advanced options again.

8. Click Startup Settings.

9. Click Restart.

10. On the Startup Settings screen, choose the startup setting you want.

This will enable you to boot into Windows 10.

Disable Fast Startup

Disable Fast Startup in Windows 10 in order to prevent Windows 10 from being unable to boot again. With Fast Startup disabled Windows 10 will take longer to boot, but it should be able boot in less than one minute.

Fast Startup is enabled by default in Windows 10. If Fast Startup is enabled, Windows 10 does not actually completely shutdown when you choose shutdown. Instead, it does a "hybrid shutdown". This is something like hibernating, it makes booting Windows 10 back up faster, but it also prevents mounting the Windows partition when Windows has not been shutdown properly.

To disable Fast Startup, boot into Windows 10 and follow these steps:

1. Open Control Panel in the Small icons view and click Power Options.
2. In the pane on the left side, click Choose what the power buttons do.
3. Click Change settings that are currently unavailable.
4. Uncheck Turn on fast startup (recommended).
5. Click the Save changes button.
6. Shutdown Windows 10 and boot back into SolusOS.

7. If you still aren't able to mount without getting errors, turn off hibernation completely. Open an elevated cmd prompt. In the search box inside the Windows 10 Start menu type cmd and press Ctrl + Shift + Enter to launch an elevated command prompt. Run the following command to turn off hibernation completely:

   powercfg /h off
