Solved PC won't boot from CD/DVD after the new update

February 14, 2018 at 08:40:10
Specs: windows
Basically, I'm no computer geek, just to make it clear.

Secondly, I know that this is an older PC it went through a ton of updates and it also handled Windows 10 well, but the more of those updates kept coming, the slower PC got. Until yesterday. (I avoided those updates, but I can't run from it forever.)

Whenever I turn my computer on, it goes well at first, but then it stops at booting from CD/DVD. It doesn't freeze, it just "pretends" to load, but it never gets anywhere past that.

I think my only hope is BIOS, but I don't want to mess with that unless I know what will help without me losing everything on that thing.

Are you saying you want to boot TO a CD or DVD and the computer balks? First question in that case would be, is the disk boot-able. Next question, is the BIOS set to boot to CD first? Your virus program may be set to scan at startup, which may really slow the computer down. Are you trying to re-install Windows?

I suggest you go into the Windows Update screens and set the parameters to update Windows and Office software ONLY. Don't use updates for hardware or third party software from Windows update. If those items NEED to be updated it is BEST to get updates from the vendors for the hardware/software.

If you are trying to access a CD/DVD while in Windows then updates may have changed how Windows 10 handles what you want to do with the disk. There are settings. If the disk is an installation disk the settings would be different than if the disk is a home brewed data disk. You can always use manual commands to open and run any CD.

Please provide additional information on exactly is happening.

Try booting into Safe Mode, while in safe mode run the following:
to be sure you are clear of malware.
to clear out junk that can bog your system down.
Use Manage Start Up Items feature on CCleaner to manage programs that start with Windows.

Restart and try it again.

What antivirus program do you have? Some like Norton and McAfee can really slow down a machine, especially one with older hardware. Try something lean and mean instead (suggestions if you like).

Otherwise more details will help us help you.

You have to be a little bit crazy to keep you from going insane.

✔ Best Answer

1. Insert the Recovery/Install DVD into the computer
2. Boot off of the DVD. When you first start your computer, the first screen you see should give you the key combination to press to enter a 'multi-boot' menu. On Dell's this key is F12 but it varries by each manufacturer. Once you find it and are at the multiboot menu, choose to boot of CD/DVD
3. When prompted (after it has booted to the CD/DVD) choose "repair my computer" and enter the command prompt
4. Type C: (with colon) and press enter
5. Then type cd c:\windows\winsxs and press enter
6. Then type del pending.xml and press enter
7. Restart your computer

That should kill any pending updates.

All that other advice about safemode and recovery, switching memory sticks, launching to last known config... does not work!!!! But the directions above do. I know, I tried everything.. this advice above actually worked, and I didnt have to reset to defaults, or reformat.
