Windows 10: Error message when installing OS

I have this old Dell Inspiron that runs Windows 10, and it can barely run it. Since I didn't have anything better to do with it, I decided to change the OS. I downloaded the MacOS Snow Leopard ISO from Internet Archive, divided it using PineTools, and uploaded it to a FAT32 formatted USB drive. I plugged it into the PC, started it up, pressed F12, selected USB Drive as my boot loader, and pressed Enter. The only response I get is a console saying:No operating system was found. Try unplugging any drives that don't contain an operating system. Press any key to restart. Is it a problem with the O

Error Message when updating from Win-7 to Won-10

Bree
I followed your suggestions (2nd Aug 19) for installing Win-10. Made the bootable flash drive successfully through the media creation tool. But when I attempted to upgrade and activate to Win-10 (64 bit) from within Win-7 (Pro-32 bit), I got the following error message:

Error # OxC1900101-Ox20017. " The installation failed in the SAFE_OS phase with an error during BOOT operation"

I read the diagnostics under this error number and carried out the proposed fixes, i.e. update Win-7, uninstall Malwarebyte antivirus, disconnect all external hardware, e.g. printer, scanner, external hard drives. I then tried to repeat the steps to do the upgrade through the Win-10 bootable flash drive as before. Got the same error message.
Appreciate any further comments and suggestions as to (a) what does a failure in the SAFE_OS during boot operation mean, (b) what can I do to solve it. Is this anything to do with the hardware in my computer? I listed these in my first posting above.
Thanks for any help

 

Windows Update Error Message 0x80070543


Ya Ya Ya, there's over a hundred threads like this, ...

Anyway, started getting this error message a few days ago, and done a lot of searching on this error message, apparently it's not, uncommon.

In particular, the (currently) 4 updates that are being affected are:

• Update for Windows 10 Version 1511 (KB3173428) - Error 0x80070543
• Security Update for Windows 10 Version 1511 (KB3172729) - Error 0x80070543
• Security Update for Adobe Flash Player for Windows 10 Version 1511 (KB3174060) - Error 0x80070543
• Cumulative Update for Windows 10 Version 1511 (KB3176493) - Error 0x80070543

The actions I've taken to date are:

1. Uninstalled firewall program (comodo)
2. Uninstalled anti-virus (Avast)
3. Reset the windows update catalog on local machine.

So the above errors are with the above done.

What other steps should I be taking to resolve the issue?

Below is notations for when I actually add to this thread.

1. Attempted to use the troubleshooter, no dice.
