Help massive problem
 

hello guys i'm new to linux i recently mooved from windows and i have single boot deepin in my machine , i was brute forcing shutdown my computer because there was an update everytime i shutdown my computer i think its from wine app because i use it to play games and i thought its just a bug , and yesterday i was trying to work on partitions i made some partitions with fdisk inside my sda3 (sda3p1) then i gave it a type (linux) then i deleted it , today morning i turned on my computer and i have a black screen with message (Minimal BASH-like line editing is supported . For the first word, TAB lists possible command completions. Anywhere lse TAB lists possible device or file completions) , i have 240g or some ssd hard drive , i type ls and i get (hd0) (hd0,msdos1) (hd1) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1) (hd2), when i type ls (hd0) i get no known filesystem detected - Sector size 512b - titak suze 7786496Kib, ls (hd1) no known filesystem detected - sector -size 512b - total size 7786496Kib, ls (hda1,gpt1) filesystem type fat - Label 'EFI' - UUID 2E0C-5772 - partition start at 1024Kib - total size 306176 KIB, ls (hd1,gpt2) no known filesystem detected - partition start at 308224Kib - total size 1571840Kib , ls (hda1,gpt3) no known filesystem detected - partition start at 1880064 Kib - total size 232549376 Kib , ls (hda2) no known filesystem detected - sector size 2048B - total size 514Kib , the msdos is my flash drive that has an iso image of deepin because i followed a thread that say if i change root to msdos and give prefix to it and set insmod normal i'll be able to boot again , but evey time i do that it takes me back to the black screen with the message , when i change my boot priority to my flash drive (make my flash drive 1st in boot order or even try to boot with the flash drive it takes me back to the bios page) . is there a way to reinstall deepin without loosing data if not its fine if i lose data just looking for a way to access deepin

Kello cunbex, & welcome to LQ.

These forums are in English, and use sentences, and paragraphs. Have a look at some of the other posts.
You will see you can do numbered lists or bullet points to set things out like partitions.

You knew what you were talking about, but not many of us did. We can take the information (if we can make dsense of it) and the error messages, and suggest to you how to fix it. We are not inclined to do the work for you.Have a read of this:

It sounds like a corrupted file system. Maybe unrecoverable, I hope you have backups somewhere.
I would reinstall. Never used Deepin, my primary goto distro is Mint, if that one doesn't work my
backup is Ubuntu. I would let the Distro format the hard disk and see if that works. I don't
know, maybe the hd is damaged beyond repair, I am not a hardware person.

Welcome to LinuxQuestions.

While it is physically possible to do this it does not work. You deleted the filesystem metadata which is used to find your files. The only way to retrieve lost data is using some recovery software like photorec or test disk. If you do not have any really important data on your system then the easiest thing to do is reinstall.

Looks like you have 3 partitions, I have not played with deepin and if it uses a separate boot partition?

If you were "brute-forcing" it to shut-down during updates, then you've almost certainly corrupted the file-system. On a standard, 'full' Linux install, this is a disastrous recipe for massive problems.

(Something like 'Puppy' Linux, which is my go-to 'daily driver', can handle this kind of abuse by simply deleting its 'save-file'/'folder', and re-booting. You have to re-customize and set things up again, but the system will happily re-boot from its read-only files. If you use mostly 'portable' applications - many of which I package specially for the Puppy community - then it doesn't even take very long to do this....)

Good luck!

Please make an effort to communicate your problem in full sentences & paragraphs. Extra points for putting code snippets in CODE tags.

Hi cunbex,

Maybe you can check if your machine has different boot methods such as "legacy" or "UEFI" and try the different options.

Cheers
