I have a PC with Windows 7 and recently updated with Windows 10.

After the update, I installed Ubuntu with GRUB on another partition

But GRUB doesn't start Windows 10. I can see Windows7 in the GRUB menu but when I select it, I get a black screen with just _ symbol in white.

I have tried to re-install Ubuntu, but I still have the same problem. I have tried to repair Windows and it says that an update is apparently ongoing and the partition is locked...

windows 10 users different boot record style GPT.

You can not install it to a drive with a Master Boot Record (MBR) Windows 10 uses GPT which is far better for large hard drives. GPT supports more than 4 partition entrys and huge hard drives

i hope this link can help you http://www.everydaylinuxuser.com/2015/11/how-to-install-ubuntu-linux-alongside.html

Try to disable Secure Boot mode in the BIOS. Shutdown your PC, than reboot and continue pressing F2 before GRUB starts, to access BIOS configuration page. Than disable Secure Boot (it may ask you for a password), save and reboot. For me it worked.
