Really slow startup and no mention of Win10 in boot

Since upgrading to Win 10 recently it takes PC about 20mins plus to start (window and revolving wheel ) then log in /admin password enter --and it then runs OK
I can live with it at worst ( make a cup o coffee and toast ) and then put it to sleep at night !

Have tried reducing progs and services that run at startup etc -but no effect on boot time

Recently examined config sys and used safe mode --but when I tried to revert to norm found that it had selective start up checked When I tried normal -it switched back to selective ?!

Under boot tab I find that whilst I start in Win 10 screen and all functions are Win 10 related --it only mentions Win7 Pro in boot
Could this be connected with slow startup time in that its saying the previous OS and having to search for Win 10 because it didnt install correctly perhaps ?

I dont want to do clean install if at all possible and have to back up / organise all files In addition I have some dongol key progs loaded that would be an absolute pain to sort out again ----but- if absolutely no other way ..............?

What would you suggest to sort
Or do I just live with the slow boot as I said earlier

Other than that -PC runs fine Its just that I`d be happier knowing if it could be sorted and whats causing it Thanks fellas (Would appreciate any suggestions and advice but please be aware that my knowledge of computers is low to average and I mainly USE `em rather than know what makes em tick!!

Initial troubleshooting is to run sfc /scannow from an admin command prompt and run chkdsk c: /spotfix or chkdsk c: /r for a full bad sector scan which takes ages. Also, ensure you have no disks connected which have an active partition other than your boot drive since this can confuse the boot process - you can use MiniTool Partition Wizard to check this. You could also use Autoruns to check and disable startup programs, services and tasks if you feel confident to use it - see Autoruns for Windows

Yesterday I posted my findings on this subject. see Windows 10 Home: Extremely Long Boot Times & Sometimes Not At All

It might help you as it did me.
Good luck!

Your partitions are OK from your post - only 1 active partition.

There may be something wrong with your configuration. Try the following:

Run start up repair - see Startup Repair - Run in Windows 10

You could try a repair install where you install Windows over itself - Repair Install Windows 10 with an In-place Upgrade

Else, you might have to do a clean install.

Ensure you have backed up your data before attempting the above.

:) . takes about 30 minutes clean, far less time to clean install than doing all lengthy troubleshooting

Yes, the clean install will take 30mins but quite a few hours are needed to reinstall all programs & devices, configure and test them.
