Windows 10: Changed language, deleted the old one. Restarted and I'm stuck into Blue screen repaid hell

Hello, I did a dumb thing .I have an old W10 laptop and I started it up after a year to get it ready to use it again, it actually was pretty fast and smooth but I was looking at a tutorial to make it faster and decided to change the language from Spanish to English, so it was easier to follow the tutorial.Installed English, and "removed" Spanish. The laptop said to restart to see changes so I did. And man, it would not boot. I enter the blue screen, first I let the auto repair run, could not fix it. I try safe mode, does nothing. I'm doing a backup restore now hoping it will fix it but I'm not

Windows 8.1 update changed the language, can't change back

Maybe, these will help... it seems it is a common enough problem.

Language packs are no longer available after you upgrade to Windows 8.1

And, sort of the same here --> Add a language or keyboard

Quote from above MS web page:

Spoiler Download and install language packs
You'll need to download the language pack if you want to make a language your Windows display language (that's the language you see most often in Windows and apps).

• Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
• Tap or click Time and language, and then tap or click Region and language.
• Tap or click a language that says Language pack available underneath, and then tap or click Options.
• Tap or click Download. The download process might take a while, depending on your PC and the size of the language pack.
  If you want to make this your display language, see the next section "Change your Windows display language".

Change your Windows display language
To change your Windows display language (that's the language you see most often in Windows and apps), first add a language, download and install the language pack, and then follow these steps.

• Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
• Tap or click Time and language, and then tap or click Region and language.
• Tap or click the language that you want to set as your display language.
• Tap or click Set as primary to move the language to the top of the list. If the language can become your Windows display language, you'll see Will be display language after next sign-in appear under the language.
• Sign out and then sign back in to finish.
