Windows 10: Windows 10 does not boot successfully without USB flash drive.

Hello, I did an oopsie by deleting my Ubuntu partition, containing the GRUB menu. I was unable to boot my PC into windows or even get the GRUB menu working of course, since I deleted it on accident Face palming. I went to my nearest store, got a 16gb sandisk USB Flash Drive, loaded Windows 10 recovery onto it using another PC, and "repaired" the boot process in the Administrator CMD on the recovery drive. I rebooted my PC with the USB Flash Drive in it, and it successfully booted into my main Windows 10 copy Windows 10 Pro btw. I wondered what would happen if I tried booting my PC withOUT my USB Flash Drive I of course fully shutdown the PC and waited a bit. It failed and a blue screen came up with a message saying my system needed to be repaired. I turned it off completely, plugged the drive back in, and the boot worked again. I need this USB Flash Drive for other things and now I have to always have the drive in the USB port on my PC forever basically until I can somehow manage to move the boot files to my main drive or something. Any help please?

Windows 10 USB boot

Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

System wont boot, trying to repair via win 10 usb installer.

Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

There is three options:
Windows 10
Windows 10 Home
Windows 10 N

Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

Also is there any other software I can load onto the usb that can repair the bootloader easily?
That would be the ideal alternative. Thanks

 

Installing windows off of a USB stick

Step By Step from vista:
From admin cmd prompt

1. diskpart
1a. list disk
2. select disk 1 (replace 1 with your usb drive)
3. clean
4. create partition primary
5. select partition 1 (replace 1 with your usb drive)
6. active
7. format fs=fat32
8. assign
9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk

 

Boot linux on USB drive

it might just be that your bios doesn't support it, but it should anyway.

make sure you go into the bios and make sure "boot other device" is enabled and try seeing if the usb is listed as an hdd.. as bootable flash drives are usually picked up as usb hdd's and check if your bios detects the flash drive.
