Windows 10: How to Do a Clean Install of Windows 10 Home - Viruses et al.

You don't get anything on screen during POST (power on self test)? That suggests something other than a software problem. (It's not as straightforward as it would have been 15 years ago: there is more interaction between the OS and UEFI than with the old BIOS.)

A semi-random suggestion: clear the CMOS.

 

For the clean install please review the steps and where you encountered problems.
Were you able to delete all partitions?
Were you able to make a fully unallocated drive?
Were you able to install Windows 10 version 1709?
When was the BSOD?
Boot to the BIOS and indicate the settings for secure boot, fast boot, legacy, csm, uefi.

 

Hi All,

1. Was able to boot from disk. I believe it is Windows Home 1709 from the link here.
2. Yes all partitions were deleted.
3. Yes I was able to make a fully unallocated drive.
4. It even showed all the four new partitions
5. Went right through to the end and troubled started on restart.
6. First time was - clock watchdog timeout and second was getting ready screen and then just a moment and BSOD.
7. Settings checked and doubled checked. See attached screenshots.

This could be why I had problems booting from disk originally. It appears the boot configuration is corrupted. The entire computer was affected by ransomware, viruses and keystroke programme. Nasty business.











Thanks bunches

SweetiePie, you may simply press F12 to take screenshots of your motherboard settings.
And you can press F5 to restore the default settings.

 

Hi All,

I only have access to the BIOS on my Asus desktop. Nothing else is working.

See below:












thanks

 

Hi All,

Tried repair and it didn't work! Nothing on my system! See below.









Thanks,

 

Hi All,


I tried to re-install Windows 10 again. It was working really well and then a "Stop Code: Clock Watchdog Timeout."

Is this a hardware problem?

Thanks

 

High there. A BSOD I assume? If so, I suggest you post here for better help instead: BSOD Crashes and Debugging - Windows 10 Forums

 

Bugcheck 0x101 is Clock Watchdog Timeout
This indicates that an expected clock interrupt on a secondary processor, in a multi-processor system, was not received within the allocated interval.
The specified processor is not processing interrupts. Typically, this occurs when the processor is nonresponsive or is deadlocked.


These were reported as 1 time fixes so there is no basis on making these universal fixes.
Reset the BIOS
Updating the BIOS
In the bios look for AHCI or SATA mode.
Change the setting to AHCI or Both.
Unplug DVD drive during windows installation

 

If you are able to boot and launch windows 10 see if you can restart while holding down the shift key. This should boot to windows advanced troubleshooting menu. Navigate to startup options > restart > select safe mode with networking > run the DM log collector > post a zip into the thread.

BSOD - Posting Instructions - Windows 10 Forums

Please indicate the steps that worked and the steps that did not work to get windows to boot.
This may be useful to others that have this problem after malware and viewers reading the thread.

 

Missing boot files right after clean installs is either bad RAM or HDD or there are still traces left from malware.

Do you have a spare drive you could use as a test?

 

For this test when it has completed please use a camera or smart phone camera to take a picture and post an image into the thread:

Run memtest86+ version 5.01 for at least 8 passes.
Memtest86+ - Advanced Memory Diagnostic Tool
This may take hours so plan to run it overnight.
Please make sure you use the Memtest86+ version 5.01 with the link below.
Memtest86+ - Advanced Memory Diagnostic Tool
The testing is done not by time but by passes.
The more passes the better.
There are a significant number of false negatives if fewer than 8 passes are made.
A false negative is a test pass when there is malfunctioning RAM.
Memtest86+ version 5.01 testing takes approximately 1 - 2 hours /GB RAM
Just 1 error is a fail and you can abort testing.
If there are multiple RAM modules that fail during testing then test 1 RAM module at a time in the same DIMM each for 8 or more passes.
When Memtest86+ has completed 8 or more passes use a camera or smart phone camera to take a picture and post an image into the thread.

Hi zbook, bobkn, NavyLCDR, Jimmyb, Matthew, HippsieGypsie and Axe0:

I believe the clean install wiped everything but didn't re-install Windows 10?? Too many BSODs.

This is way beyond my skill level. Therefore, I'll need to take my desktop tower to my local computer chap to fix.

Thank you every so much for all your help. zbook many many thanks.*Cool

Cheers, *Wink
