Aspire XC-605 No bootable drives after BIOS update

Hi,

I installed Windows 10 on my Aspire XC-605 yesterday. I could not get the sound to work after that. I saw in another discussion that a BIOS update was recommended.

So, I updated the BIOS to P11.B4. The update went fine, no errors reported. Upon rebooting, I went into the BIOS settings and loaded defaults as recommended in the README file.

However, my system no longer sees a bootable hard drive. Every time I reboot, I receive this message: Reboot and Select proper Boot device or Insert Boot Media in selected Boot Device and press a key.

If I go into Advanced -> Miscellaneous in BIOS, my hard drive is definitely shown in AHCI Port2. In Boot Options, the 1st Boot Device is set to Hard Disk. But when I go into Hard Disk Drive Priority, there is nothing listed at all.

Any suggestions? I have a brick right now.

Well, I'll be ... I figured it out after several maddening hours.

I googled and found several similar stories for this error message, and everything seemed to be leading to me needing CSM enabled. I had noticed that the Launch CSM setting in BIOS was grayed out and set to "Never" in the BIOS.

I finally realized that disabling Secure Boot allowed me to toggle the Launch CSM setting. I then set it to "Always". Everything seems to be working now.

<div class="QuoteText">A. The Windows GUI utililty (afuwingui) is for experts. Are you an expert? Most people that have BIOS problems or brick their XC-605, TC-605, Tc-705, xc-705 use Afuwingui. You're lucky you didn't brick it. I read the readme and use the SOP and don't have any problems. The standard operating procedure (SOP): 1. Download P11.B42. Extract3. Copy the Win and ROM folders to a USB flash drive.4. Open an admin command prompt5. If your USB flash drive has a drive letter of F, then you would type F:cd winflash 6. After the processing completes, restart your computer7. When it prompts you to enter the BIOS, press the "delete" key on your keyboard to enter the BIOS settings8. Load the BIOS defaults (F9) and then save/exit (F10).---------------------------------------------------------------------------------------------------------------- B. If your computer came pre-installed with Windows 8, Windows 8.1 or Windows 10, don't disable secure boot and don't set launch csm to always. Good luck </div>

Hi, sorry but I really need to hijack this post. 😂 I kinda used the mentioned afuwingui.exe to flash the BIOS which resulted in a dead unit of XC-605. Is there a way to revive it? Thank you...
