I have a problem that requires urgent solving, since I need both a 64 bit Linux and windows 10 running asap since I have to log in to work from windows, but I also have some other work on 64bit Linux
As listed in the title, I had windows 10 education and needed a Linux to dual boot....I first screwed up by using my old mint 18.3 on 32 bits to install to go with windows, so I realised I need a new 64 bit CD, so i destroyed the Linux partitions from windows 10, and when I restarted I had a crashed GRUB command line...and from here a long list of trouble which is tormenting me and costing me money for 2 days. I have written a mint 21 vanessa CD on 64 bits, but when installing from the CD it could not write the bootloader on /dev/sda, as was the default option....I have tried reinstalling several times. Could only get back to windows when installing mint 18.3.
I have noticed some firmware errors when logging in and out of linux also.
I have planned to repair Windows with a windows 10 recovery disk, but I could not, I have tried all the options there, but none work, includeing the firmware and some commands from the internet, some worked and some not, which resulted in the computer now booting in the network mode, as nothing from the hard drive seems to work.
Before this crash I have tried installing mint 21. over windows and linux18.3 which were working but I couldn't because it tried to write the bootloader again and failed with fatal error. Before starting the install, mint21 only detecte mint 18 as an OS. I ended up with a new 500MB ESP boot partition which was visible as fat32 drive E: in windows.
So i installed mint 19.1 and it worked, but when the PC rebooted it was going directly in mint. During the installation proces it said no OS detected.Found some commands in other results, update-grub something and now I have 4 options, or related to mint 19.1 the menu when pressing FN + F12 on my laptop for BIOS option and boot order has been diminished.
I have an ubuntu efi in that list, which says it can not boot if i try it, probabily the failed grub from previous crashes.
The partitions and the files are accesible from Mint 19.1, just can't find the OS to boot it
found a utility os-prober that does not give any output.
Other outputs that may help:

sda2 is the main windows partition C:, sda1 system reserved and sda3 windows recovery.
sda5 is what i got after puting, mint21 at some point over windows with mint 18.3 the E: mentioned earlier, would it be better if i just delete it?
https://ibb.co/F5JxtVT
AFAIK I have both system installed under Legacy, at least the Mint 19.1

didn't see firmware issues when loading, but it still doesn't find windows partition.
will installing a new windows 10 over the old one (so i can keep my user and data) help fix the problem? Window repari with all the other optons didn't work.
. And it moves 20 times slower than linux as it did....
