I installed Ubuntu on a system that has Windows 10 installed. I can boot to Windows or Ubuntu normally using GRUB. I want to delete Ubuntu partition, but first I must restore the Windows 10 MBR.
In Use Bootrec.exe in the Windows RE to troubleshoot startup issues (applies to Windows 7 and Windows Vista) they say to use Bootrec.exe with options /FixMbr
/FixBoot
, but when I type "bootrec.exe /FixMbr" in a command prompt, Windows says:
'bootrec.exe' is not recognized as an internal or external command.
I say I can boot to Windows 10 and run a command prompt from there (I don't need to use an installation medium), but I don't know what to enter.
A quick fix is to boot into the installation media anyway to run bootrec. (Perhaps someone else knows of a solution that doesn't require that.) – Maximillian Laumeister – 2015-08-02T04:10:45.913
I have 5mbs, so I'll take me ~3 hours to create Win10 usb boot, I thought I could fix MBR from Windows, like EasyBCD utilty does (not working yet for Win10) – Codyfly – 2015-08-02T04:28:26.233
It might be helpful to edit your question (and its title) to specify that you're looking for a solution that doesn't involve the installation media. I just gave you an upvote, because I'm also curious if it can be done. – Maximillian Laumeister – 2015-08-02T04:35:22.267
I finished downloading Win10 and fixed installation via command prompt on recovery disk – Codyfly – 2015-08-02T06:02:38.430
Glad to hear it, and apologies I couldn't help you do it without the install disk. – Maximillian Laumeister – 2015-08-02T06:03:51.577
