HP ProBook stuck on undoing changes

[Dutchrys]

So, I currently use a HP ProBook 6555b and I was in the middle of installing a Windows 10 update. However, the update took way too long for me, so I decided to restart my laptop, and now it is stuck in an infinite loop saying "Undoing changes you made to your computer." 

I cannot get into safe mode. None of the F keys work to get into safe mode, I cannot reset my laptop, there is no system reset, and I do not want to get a USB with Windows 10 on it, nothing. I want to find a solution to this problem without having to go to the store and paying to have this issue fixed.

You did this to yourself by shutting off the PC while it was doing updates.  I think that MS put the message to Not turn off your PC during updates to prevent this kind of thing from happening.

There is no simple way to undo the corruption because some Windows system components now are incorrect.  You would have to rewrite all of them to be sure to get a working system back.

Since your PC can not successfully do an internal factory reset, your only ways to accomplish this are the following:
- Factory reset using external HP image you make
- Factory reset using external HP image you buy

Each of these is discussed in some detail below ...

---------- Factory reset using external HP image you make ----------
HP provides a Cloud Recovery tool that you can use, together with a 32GB USB stick, to create your on HP reset media.

This works the same as the factory reset described above.

---------- Factory reset using external HP image you buy ----------
For those PCs not supported by the Cloud Recovery, in some cases, HP offers Recover Media for sale. This can not be downloaded; instead, it must be ordered from HP.

HP Recovery Media is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utilities.

In some cases, you may be able to order a USB stick instead of disks.

You can look online for Recovery Media starting with the linked paged: http://support.hp.com/us-en/drivers

Once there, input your Product name or number. On your Software and Drivers Download page, select your Operating System and and Version. Click &quot;Update&quot;.<br><br>If HP Recovery Media is available for your machine, down near the bottom of the page, you will see an entry for Order Recovery Media-CD/DVD/USB. Click the &quot;+&quot; symbol to expand that entry and click on Order Media for details.

Or, if you prefer, you can do the same by contacting HP Customer Support.

HP contact info: https://support.hp.com/us-en/contact-hp?openCLC=true

If HP no longer carries the media you need, another site you should check for HP Recovery Media is: http://www.computersurgeons.com/

These work the same as the factory reset described above.
