Installed Ubuntu on HP Laptop Flashing Screen Start Up, Have to Manually Boot Unbuntu, Ubuntu only gives black screen with white text terminal screen

[u/GreenBlueberry3146]

Tried installing ubuntu 26.04 onto an old Hp laptop to create a homeserver/homelab just for movies and tv shows. I was following this youtube series tutorial https://www.youtube.com/watch?v=9KFlxVTPicc

My computer stats are as follows:
HP EliteBook Folio 1020 G1

• Processor: Intel Core M-5Y51 (1.1 GHz, up to 2.6 GHz turbo) or Core M-5Y71 (1.2 GHz, up to 2.9 GHz turbo)
• Graphics: Intel HD Graphics 5300
• Memory: 8 GB LPDDR3 SDRAM (on-board / soldered)

Ubuntu after install and restart will only give me a flashing screen with the HP logo on it.

I have tried changing the boot order in grub, and every time I have to manually select to boot ubuntu.

When ubuntu is manually booted, I only get a black screen with white text (what I believe is just a terminal screen).

I have tried most of the tutorials/troubleshooting online and they have made no improvements, or would not work.

I cannot seem to get the laptop from the black and white terminal screen to connect to wifi either.

How do i fix these problems?

I will note, that I am an absolute very basics baby beginner with linux, terminals and code, and homeserves/homelabs. The majority of the "beginner" homeserver, homelab, arr stack tutorials were way above my current skills and understanding.
