Strange Windows 10 behavior at startup

Hello everyone,

I'v got a ASUS N73SV laptop on which i upgraded 3 months ago from Windows7 to W10
From now I had no special issues with it, but since 2 days my computer has a abnormal behavior at startups, and depending the startup mode:

- When I shutdown it 'normally', at the next reboot Windows startups normally BUT at any applications, I have NO right*click menu allowable (it looks like it loads it but it stops as quickly).
No way to use the computer normally, no copy/paste allowable (eg. a Google search), not possible to type some admin commands in DOS huhhu...
Nothing could could be done normally
- When I restart it (related button 'restart' / hard reboot (!)), before the W10 startup the BIOS prompts me on what disk I want to startup (the laptop got intially 2 disks and 1 DVD device).
I have to choose one otherwhise nothing happens.
I then choose the first disk (default on), Windows 10 startups normally and I DON'T have the right-click issue with a normal startup (see above for a description). All the computer is fine and could be normally used

I've looked for a malware (malware bytes), virus (avast), adw cleaner. Nothing found
Ran Wise Disk Cleaner. nothing better after
Did a system restore before the last Windows update schedule 3 das before. Same behavior.
Did a SFC /SCANNOW then a DISM.exe /Online /Cleanup-image /Scanhealth. Nothing found
No specific event in the Windows10 logs....
I made no specific installation just before or something else that may be wrong for Windows

Any clues guys regarding that behavior at Windows startup ?

Really appreciate you help on this !

Hi dalchina

Thank you for your quick reply regarding this issue

I prefer not to remove the second drive - contains some data but never a OS (or maybe the partition to recover Windows with the initial OS - Windows7

I attach the results of commands diskmgmt.msc and CHKDSK C: /F (at reboot). It looks like there is nothing suspicious if I'm correct with the output reading (also attached)
Insteaf of removing the other disk I prefer to perform a Repair Install of Windows eventhough I had some pain to migrate from Windows 7 to W10

I'll keep you posted when I will did that - unfotunately it takes some time and I have to backup some stuff before doign the operation
Let's try with your tool you advise and the tutorial

Best regards

Dominique

ps: sorry but it's French language in the output files

Hi, I note

I would guess your second disk may in the past have had an OS on it, and you may have to examine its characteristics in diskmgmt.msc.

Please post a screenshot as follows:
Windows key + R to open the run box
Type
diskmgmt.msc

and post a screenshot of that.

========================
If you remove the second disk, does your PC boot normally?
========================
Finally if not, as you've tried system restore unsuccessfully, I would first

Check your hard disk.
From an admin command prompt (I'll assume you can open one else research how as I'm not sure which route is limited for you)
run
chkdsk C: /F

If clear, then try a very good repair technique, one of the best features of Win 10 (I think):
Repair Install Windows 10 with an In-place Upgrade - Windows 10 Forums

This
- keeps all your programs and most settings
- creates Windows.old
- can take a long time, depending on your hardware (it's virtually a Windows installation)
- turns off system restore
- means you have to redo Win updates from November (perhaps total 3 or so)
- may mean you have to set up or Wifi connection again (if you have Wifi)

It's very useful to keep a bootable version of Win 10 for this and other reasons.

I recommend for safety that you create a disk image of what you have now BEFORE doing this, and maintain your disk image thereafter so you can quickly restore your PC to a working state without technical help.

E.g. chdsk_C.txt

Good luck.

Hi,

The result of the diskmgmt.msc command to me seems normal since this is the initial base configuration of this laptop: 2 physical disks with several partitions inside of them.
Regarding the issue itself I encountered I well noticed your advices but - and that's a good news !- I had to use my laptop several times since Monday and the problem -seems- have disapeared by itself I have no explanations of course by the phenomenon since I also did nothing (no time to try a Windows repair just read the tutorial...)
I have to close the thread because it has no meaning to maintain it open.
Thanks a lot for your help

Hi, I'd expect your C: to look more like this:


Try a startup repair and see what happens.. after that you need someone who knows more about partition layout.
(Mine's UEFI).

Hi all, I know this is an old thread, but I know folks are still upgrading from Windows 7 to Windows 10, so it is pertinent. I have done the Windows 7 to Windows 10 upgrade on a number of desktop computers with no issues. However, on my MSI laptop, I had nothing but issues after upgrading. I finally did a full backup, made sure I had all of my application reinstallation media and keys and did a full Recovery reinstallation of Windows 10 (wipe everything, keep my data files). After reinstalling all of my applications, the system is now stable and working great. So, just a word of advice, consider doing a clean install of Windows 10 to minimize OS issues. I know that it is a royal pain in the butt, however, it is something you should only need to do once.
