microSD boot-kinda

I have a 128 GB micro SD card that I wanted to use as a secondary boot drive to the internal SSD.  It's pretty fast and not as expensive as a 128 GB SSD that's M.2 SATA size...plus I already had it for a RPI.  I partitioned it so that I have a bunch of other Linux OS on the micro SD and made a bootable EFI (esp) partition.  I installed all these free Linux OSs but could not get them to boot from rEFInd using the SD card slot with the included adapter.  I found a workaround, though.

The card will boot, just not from the SD card slot.  I have another adapter that plugs into the USB slot and allows u to plug a standard size SD or micro SD card into it.  This is what I used and is 3.0 USB so it can go fast:

  All the Linux OSs are now found from the rEFInd menu-so there is no need to press [F7] to get to the boot menu because once installed rEFInd finds it.  I did uncomment the 5 second delay in refind.conf but I'm not sure that's needed.

I'll post some pictures and screenshots a bit later.  Maybe that SD card slot is bootable with rEFInd?  I was told it is but I'm not sure how.

Well, I don't quite understand the boot screen or the rEFInd screen on this PC.  I have 5 OSs installed on my system but only 4 show up on the screens and not at the same time.  I have Mint on my SSD and on my micro SD card I have Elementary, Neon, Ubuntu, and Peppermint.  Windows doesn't exist but still shows up on the boot screen??  Here's pictures of what happens-note that Peppermint does not show up.  Maybe someone can explain these quirks...oh and this rEFInd screen only shows up this way when my micro SD card is plugged into a USB adapter (click to enlarge):

So why don't all 5 OSs show up on the boot screen and how do I edit this?

Hi Marty,

Have you found a solution for booting other Linux SO from microSD? I'd like to install Peppermint OS on my N42 without removing Windows.

Thanks,
Dario

Have I found a solution...kinda.  But not Peppermint OS for me.  It will boot another OS from the SD card slot with a micro SD card and adapter.  I'm not sure how it decides which OSs it'll boot.  Maybe it would be different for somebody else that doesn't have so many distros installed on the micro SD.  I can have it boot KDE Neon, Ubuntu and Elementary.  Since Ubuntu is what all these are based on, I would think that Ubuntu would boot off of that SD slot for anybody.  I did post a version of Ubuntu with the XFCE desktop if u don't like the regular version of Ubuntu that is also available on this forum. 

Have u seen this thread I made that shows u how to make some other Linux installs from an official iso?

I don't think I ever made a live USB for XUbuntu, but that distro is based on Ubuntu and is fast like Peppermint.  If u need me to build this, I could do it this weekend.  Let me know!
 
U can also download any desktop to Ubuntu with apt-get or synaptic.  This talks about how to do it for an older build of Ubuntu but commands should be the same.

EDIT:

Also, u may have to look into the rEFInd boot manager to get things to boot the way u want.  The Ubuntu thread HERE shows how to get it installed (bottom of the OP) and this LINK shows how to configure refind.conf but I cannot get these options to work.

Thank you for your explanation!
I think I'll go for regular Ubuntu or Linux Mint... at least for a while.
