burn again or create one installer

[Mio Larso]

Made again and getting the same error I even redownloaded the whole thing and still not working 

[dnakruemel]

After DL, confirm Hash of downloaded file agains Hash listed on Download link list.

Then, did u use etcher to burn? (Etcher confirmes written image is free of error, not all image writers do that)

 

So u can be completely sure ur installation media is bit perfect to what's intended by uploaded file.

 

EDIT: make sure to calc Hash on .raw file not the containing .zip. (Zip will give other Hash as result)

My hash is on the raw not the zip I tried to even re-download it and yes I used etcher now I have no idea 

Ps the terminal time trick didn't work 

[dnakruemel]

If the hashes match theres no need to re-download, the file is fine then.

If etcher throws an error at the end (after validation), theres a good chance the drive will boot anyways - with a broken OS. So id recommend flashing again and closely watch the final message of etcher. If etcher says validation is fine, then its device specific and u depend on the real pros like maldon.

Trying on another USB drive and going to carefully see what etch has to say

[Mio Larso]

so i finally found a solution and it worked quite well 

I used a new Flash drive and it just went through perfectly , I have no idea why my first 2 drives didn't work , now I will go and start tweaking with the EFI file 

 

any recommendations?

Use Olarila efi for ur chipset for one good and clean start
