Hi,
My Aspire 5 (A515-51G) is not working as it says "No Bootable Device Found". I have it checked at a computer repair center.
Firstly, they reinstalled the windows + Bios to make sure it was not software issue, and the laptop worked for about 2 days then it shut down suddenly. That same problem came back the next time I turned it on. Brought it back to the shop, this time I've got the hard drive replaced. Same thing happened as it worked for 2-3 days then shut down unexpectedly while was in use, it was "No bootable device found" again.
I have no ideas how to get it fixed, and the shop refused to help me further as they said they could not get it done and it seems not fixable

(((
I do not have money to buy a new laptop in this hard time, and would do everything to save this laptop to carry on with my study.
Please help. I am not a pc guru by the way.
Thank you very much. Deeply appreciate any help.
