Unable to boot
« on: Sun, 19 March 2023, 03:23:55 »
Hey there ! I have a problem I think you can help me with. I have a Toshiba satellite a300 1G5 and I installed ssd in it. After that  my usb stick is unrecognized in the bios and I can't boot from it to install windows from it. And I marked it as active using diskpart and still nothing.
The error message is "active partitions not found . Press any key "
Thanks.

My first guess would be a faulty USB drive.
Can you check it in another computer?
"Donald Trump is the most dangerous candidate for president in my lifetime.
His disdain for the sanctity of our Constitution, the sanctity of democracy, the sanctity of the rule of law, and the sanctity of the peaceful transfer of power should disqualify him from the office of president ever again. He doesn't understand the meaning of this country, its history, or what it means to be deeply American."

This thing happens every time I install SSD into it. When I remove the SSD and put the HDD back everything is normal and the USB boots.

I have one laptop where it will ONLY boot the USB from a cold boot.
If you reboot, no matter what, it will not allow you to boot from any external device. You have no idea how long it took me to figure that one out.

Another problem could be the formatting and how Bios handles it. The bios may be switching to UEFI/GPT/secure boot once it sees a properly formatted drive (i.e. the ssd). Look in the bios and see if there's an option to allow MBR or legacy boot. This option may only show up if secure boot is disabled as secure boot requires GPT formatting.

bios has alot of hidden settings they lock away from us.

In some cases it's good to hide those settings away, I have seen people mess up things to cause boot/post issues. 

I can bet they dont have the Boot from external media/USB setting enabled - alot of machines have this disabled by default.  Normally this setting is in the boot/system menu in the bios.
