Welcome to the forums

Why Linux fails to load/install direct to HDD, common reasons
1] Corrupt download [check SHA sum]
2] bad burn to installation medium [try again] [if you used Rufus then try Balena Etcher]
3] Wind 8.2 and higher quick start/fast boot or secure boot not disabled [doesn't normally apply to older versions]
4] defective pen-drive/DVD
5] hardware fault,
5A] If old style HDD run integrity check
5B]if SATA SSD check for hidden partition at the beginning of drive [this will stop Grub from loading] and delete it before re-installing Linux
If M2.NVMe check, your system is NVMe compatible [not all older kit is]
That SGX is normally enabled by default.
Did you mess with the bios recently ? or used something
Doesn't look like a Ubuntu problem. More as a semi-broken bios.

Try F5 in bios to load optimized, then F10 to save and exit.
Your bios could have different keys, look for which one is which.
@aliahmad, you could try a few kernel options such as:
Only try one at a time.
For guidance on how to add the kernel option to the linux line, see here:
You may need to install intel-microcode
To just turn off these messages, you may edit /etc/default/grub and add to the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and add the parameters acpi=off or noacpi acpi=strict and then run sudo update-grub.

You can also run fsck to check your OS - your disk needs to be unmounted to run this so do it from a Live thumb drive with your OS and boot from that once booted open a terminal and run sudo fsck -p /dev/sdXX where XX is you drive (sda1) generally you can use -p to allow fsck to automatically apply repairs
