Toshiba Satellite L50 ssd appears/disappears in bios

[strelokstk]

Hi, i have a Toshiba Satellite L50-A-1D6 and i bought a Kingston V300 120 GB SSD.
The problem: turn the pc on, bios set at its defaults, install windows using a usb pen formatted with rufus using uefi. Installation completes, it restarts, windows won't load because no bootable device is found. I go into the bios and the ssd doesn't show up anymore. When i reboot it never shows up. But if i turn the pc off and then on it works. But sometimes it doesn't. Now, it could be the ssd, but i tested the ssd in another pc and it worked (installed win on it). This pc where i tested it had another ssd with win installed using uefi and the bios had the correct settings. On the toshiba i tried changing CSM boot to Uefi boot but nothing after the installation but nothing. I add that at the first try, before installing, it was set to Uefi boot and ssd did not show up. I changed it back to CSM, saved, exited the bios, went back into it, and it SHOWED up.

Something like this never happened to me, i don't know if it's the ssd's fault of the pc's. Any ideas? Thanks.

If your boios setting have the following choices try them Worked on an asus.
Security Options of the BIOS and disable "Secure Boot"
Try this if not already done go to the Boot section of the BIOS and
- Disable Fastboot.
Keep this setting- Enabled CSM (Compatibility Support Module)
You probably have already tried this combination already..

Hi,
I'm Jewel with Kingston Technical Support and would like to offer our assistance. The issue described sounds like a firmware incompatibility that has been found to affect a few systems. It is not known for the Toshiba L50 but the reboot symptom matches and if your V300 has firmware version 600ABBF0 than that may be the issue. Please contact us so we can confirm this and provide you with a resolution. Reach us at 1-800-435-0640 (USA and Canada only) M - F 6am - 6pm PT and an available technician will assist you.

Thank you for using the V300.

Thanks for help but i cant call that number, i live in italy xD. I checked the firmware version and it was the latest. I read somewhere that only kingston can downgrade it. My friend ehi is the owner of the ssd decided to return it to the seller. Thanks for helping.
