cant boot into windows 10 after installation of LINUX mint

[MikeInMexico]

OK in SuperGrub2:
If I select "Windows Vista/7/8/2008 (R2) ... (hd0,msdos1)" I get the Windows dual-boot menu which allows me to boot Windows 7 or 10. If I go down to my "Windows 7" entry, I get the same flashing cursor, no boot.

The boot-flag (active partition) has set to the wrong partition. What tells

Windows 10 has changed the boot order, so you need to boot into Windows 7, run msconfig, where set Windows 7 as the first option. An example picture about msconfig

Did that but it really didn't help. Now I get 7 but not 10. But I've fixed the problem. I ran fixmbr to get rid of grub then deleted the Mint partition. Now I'm back to where I started before the install. Thanks for all your help, but this whole thing is just too much trouble. My students will have to do without their glimpse of Linux for now.

I was dual booting Linux mint with windows 10 and seems like I installed grub into EFI partition. First, I could not see an option to boot into windows but after running "sudo update-grub" I can see the windows boot option like the one on my laptop but it does nothing while selecting. It takes me back to grub again and again.

seems like I might have wiped uefi-partition?

What can I do rather than going for a fresh install?

You should make a new topic.
