Bios not detecting ssd

Hello. My PC was working fine until one day a blue screen appeared with a stop code 'WHEA_UNCORRECTABLE_ERROR'. When PC restart it shows 'Reboot and select proper boot device'.

I checked bios and it couldn't detect the m.2 ssd(windows installed). I tried several restarts and reinserted ssd and it solved but then this issue became frequent.

I reinstalled windows thinking if it was any software issue and PC was normal for few days. But later this issue occurred again.

I'm no more able to boot my PC. I don't know if my ssd is damaged, I bought it just 2.5 years ago.

 

SSD is not detected in BIOS

Hello! My name is Cristiano. I'm an Independent Advisor. I'm glad to help you.

Fahad, please make sure that all the cables connecting your SSD to the motherboard are securely connected. If the cables aren't connected properly, the BIOS won't be able to detect the SSD. Also, check that the SATA port on the motherboard is working properly. You can try plugging the SSD into a different SATA port to see if that resolves the issue.

You can also try resetting the BIOS to its default settings. Sometimes, the BIOS settings can get messed up, causing it to not detect hardware properly. To reset the BIOS, look for a reset jumper on the motherboard or remove the CMOS battery for a few minutes.

It's also possible that there's an issue with the motherboard itself. In that case, you might need to contact Acer's customer support or take it to a repair shop to get it checked out.

I hope that helps!
