Question MBR problem after ubuntu uninstallation

[faustthedog]

hi,
tried to get rid of Ubuntu and stay with win10 64bit (previously have both systems installed)
The result is: my MBR doesnt exist.
In the normal mode i still have GRUB (ubuntu bootloader) command line.
In the UEFI boot mode from USB stick (with win rescue installation) i can go into win10 .
Have full access to my HD.
Any ideas?

Computer is DELL Vostro 7570 with Win10 preinstalled

You should able to rebuild the MBR, https://www.pcworld.com/article/311...ster-boot-record-and-fix-your-bricked-pc.html

i tried bootrec /fixmbr before. it doesn't work, unfortunately....
i tried also:

1. Bootrec /fixmbr
2. Bootrec /fixboot
3. Bootrec /ScanOs
4. Bootrec /RebuildBcd

after step 3 there is info that win10 installation was found
after step 4 there is info there are many objects and its impossible to choose proper one (sorry, i dont have an exact phrase of the error text)

Hopefully there is a fix somewhere in this link. https://superuser.com/questions/1294071/how-to-recover-the-windows-10-mbr-after-w-linux-install including

You can reinstall the Windows boot manager by booting off Windows bootable media.
Press F8 while booting the system to go into the Windows Recovery Menu. Unlike other version Windows 8’s recovery menu has the Metro UI style.

• Click on Troubleshoot.
• Click on Advanced options to get into Automatic Repair menu.
• Click Startup Repair

This will return the Windows bootloader, but remove the ability to boot Linux

@onespeedbiker thx, but the point is also that i have no possibility to go into recovery menu, f8 during boot doesnt work
tried also to use command line and do

bcdedit /set {default} bootmenupolicy legacy

but have the response like "The boot configuration data store could not be opened."

I think you missed that you boot with an installation media, not your hard drive.
