hello I yesterday installed ubuntu alongside windows 10, after finished using ubuntu I wanted to restart and boot into windows 10, but i failed to boot up and switched to ubuntu GRUB, i chose to boot windows boot manager, and same thing, it switched me to ubuntu again, i noticed that and tried again to boot into windows boot manager, but thsi try I said under the loading " preparing automatic repair" and took me to repair setup. I didnt know what to do only to use a portable flash drive and install windows files in it and repair the PC, and during the installation, I tried to boot into BIOS and see if I can do something, I went to boot and noticed that there is an OS list and ubuntu was at the top, so I changed it to make WBM at the top and tried to boot to windows 10 and I was able to. and today I set ubuntu to the top and tried to boot into ubuntu and I was able to, after an hour I didnt make any changes to the BIOS setup and tried to boot into windows and I was able to????? what is going on to my laptop???? by the way its an acer nitro 5 AN 51

  • Can you provide the exact model? Example an515-51-75kz. Also, does the same problem occur when disabling fast startup in windows 10 power options?

  • Mr Batmalin has already responded. I also recommend not using hibernation, sleep and hybrid sleep when windows and linux are in dual boot mode.
