Grub rescue does not open the boot folder

I recently installed Linux Ubuntu 22.04 on an external SSD (through a USB memory, with Rufus)

When start I find this:

error: file '/boot/grub/i386-pc/normal.mod' not found 
Entering rescue mode 
grub rescue>

I start to investigate where the file is

error: file '/boot/grub/i386-pc/normal.mod' not found 
Entering rescue mode 
grub rescue> ls
(hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)
grub rescue> ls (hd0)
(hd0): Filesystem is unknown.
grub rescue> ls (hd0,gpt2)
(hd0,gpt2): Filesystem is unknown.
grub rescue> ls (hd0,gpt1)
(hd0,gpt1): Filesystem is unknown.
grub rescue> ls (hd0,gpt3)
(hd0,gpt3): Filesystem is ext2.
grub rescue> ls (hd0,gpt3)/
./ ../ lost+found/ boot/ swapfile etc/ media/ var/ bin dev/ home/ lib lib32 lib64 libx32 mnt/ opt/ proc/ root/ run/ sbin snap/ srv/ sys/ tmp/ usr/ cdrom/
grub rescue> ls (hd0,gpt3)/boot/

grub rescue> ls (hd0,gpt3)/boot/grub/

error: file '/boot/grub/' not found.
grub rescue> ls (hd0,gpt3)/grub/

error: file '/grub/' not found.

Using "Try Ubuntu" of the USB memory I can access the SSD and find the path specified above (/boot/grub/i386-pc/normal.mod)

Why can't Grub Rescue find it?

Notes:

BIOS or UEFi?
I accessed the BIOS and not found a mention of UEFI (It is a low cost desktop PC from 2011).

Hardware? the motherboard is a MSI NF725M-P43

The SSD is Samsung M3 Portable 1TB

Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed. Use often updated ppa version over somewhat older ISO with your USB installer or any working install. https://help.ubuntu.com/community/Boot-Repair &

I try use the Boot Repair with the installer in the usb memory. But i have this error: "The current sessions in BIOS-compatibility mode. Please disable BIOS-compatibility/CS/Legacy mode in your UEF firmware, and use this software from a live-CD (or live-UsB) that is compatible with UEFI booting mode. For example, use a live-USB of Boot Repair Disk-54bit (wwnw.sourceforge.net/p/bootrepair<d), after making sure your BIOS is set up to boot USB in EFI mode. This will enable this Feature" But in the bios I could not find any function of "Legacy", "Secure Boot" or similar

Hello, I was finally able to solve the problem by installing Ubuntu and doing the partitions manually. (I used the automatic installation before) I did this: /boot 1 GB, /efi 1 GB, /swap 8 GB (double the ram), / (root) 100 GB, /home rest (approx 890 GB)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
