Booting from hard disk in CD Bay

[syncswim]

I have an old laptop which does not allow booting from USB. I installed PLOP boot manager on the internal HDD and the machine now boots linux happily from an SSD attached by USB. So far so good

Seeing as the 'client' is happy with this Linux installation, I bought a caddy which replaces the dead optical drive. The external connector is IDE, the internal connector is sata. Having booted linux from a pendrive I can see that the drive is detected and working properly.

But here's the problem. When I choose to boot from CD in plop, it says no CD is detected. I guess that makes sense as there is no CD, but an SSD where the CD would normally be.

I should mention that this disk is formatted to EXT4.

How can I boot from this disk?

Thanks in advance

Hello,

the CD option is only for IDE CD/DVD drives. USB optical drives are not supported by the USB driver.

when you boot Linux then you can use PlopKexec instead of the Plop Boot Manager.
