Help with Inaccessible boot device 0x7B error code on Aspire 515

vuski2015

Hello,

My son inadvertently installed an Intel update that now rendered the laptop no longer working. After the install, the laptop rebooted and a black screen came up with some error msg, and the machine indicating it's trying to reconnect to a network (wifi?) and gave a waiting time of 30 mins. After the 30 mins had passed, the machine rebooted again, and continued..I decided to factory reset by following the repair instructions, and the machine completed the factory reset, wiping out everything on the hard drive. Now the laptop attempted to reboot but only with the inaccessible boot device 0x7B error code and that's where we're at right now.

Here's the following specs on machine:

Win 11 Home

BIOS version v1.36

400GB HDD

I attempted to go into BIOS and looked around but didnt find anything that I could do to fix the issue.

Here's hoping to receive some help from the community. Thank you very much!

1. Restart your laptop and press the appropriate key to enter the BIOS/UEFI setup. On an Acer, this is often F2 or Del during boot.
2. Navigate to the "Storage" or "Advanced" settings and find the SATA controller mode.
3. Ensure the mode is set to AHCI. If it was recently changed to RAID or IDE, change it back to AHCI.
4. Save your changes and exit. The laptop will restart.
