[Is XPEnoboot required permanently?]

Sorry in advance for this question, but I hope its a striaghtforward question for you to answer

 

I have a HP Gen8 microserver and am installing XPEnology direct to the box, no vitrual environment, I dont think I need it.

 

I have managed to get XPEnology installed to the single drive I currently have in the system, via the MicroSD card with XPEnoboot installed.

 

The system is up and running, however I was under the impression once installed the system was installed to the main drive, and hence I would no longer need the SD card. However after removing the microSD it fails to boot.

 

So am I right in saying the system will always need a microSD (or USB key) in the system in order to launch the software?

 

Thanks

[XPEnology on HP Proliant Microserver Gen8]

I have just ordered on of these, with a plan to use XPEnology

 

I was hoping I could install it to a MicroSD card. Is this possible, and is there any disadvantage over install to a USB. Also the card I have is 16GB class 10. Is this enough?
