Where can Linux boot from?

Linux can definitely install to a partition on the SD card.  I'm just not sure how to get rEFInd to boot it.  I partitioned my 128 GB microSD (it has an SD adapter) into about 4 ext4 30 GB partitions.

Here's a screenshot:

 There's a bootable/EFI FAT32  partition on the installed SSD card for booting.

Any ideas?

All these commands were done in root session:

sudo -E su

I'm thinking this line needs to be customized in /boot/efi/EFI/refind/refind.conf but I'm having trouble getting it to start the first partition of my removable microSD card:


Code:
menuentry Linux {
    icon EFI/refind/icons/os_linux.png
    volume 904404F8-B481-440C-A1E3-11A5A954E601
    loader bzImage-3.3.0-rc7
    initrd initrd-3.3.0.img
    options "ro root=UUID=5f96cafa-e0a7-4057-b18f-fa709db5b837"
    disabled
}
using blkid I have this:

Code:
/dev/mmcblk0p1: LABEL="Elementary OS" UUID="d4ebed1e-3270-42cb-9971-be714f87ef4c" TYPE="ext4" PARTUUID="155724db-01"

Elementary OS is on my microSD first partition and this is in the boot directory:

tux@Apollo-N42 /media/tux/Elementary OS/boot $ ls -lh
total 60M
-rw-r--r-- 1 root root 1.4M Aug  9 07:08 abi-4.10.0-32-generic

-rw------- 1 root root 7.1M Aug 14 15:36 vmlinuz-4.10.0-32-generic.efi.signed


I tried this but don't see it on reboot:


Code:
menuentry Elementary-OS {
    icon EFI/refind/icons/os_linux.png
    volume 155724db-01
    loader /boot/vmlinuz-4.10.0-32-generic
    initrd /boot/initrd.img-4.10.0-32-generic
    options "ro root=UUID="d4ebed1e-3270-42cb-9971-be714f87ef4c"
    disabled
}
What am I doing wrong?  I'm used to the grub bootloader so maybe I'm doing something basically wrong with rEFInd.  I think the problem is on the volume line.  Arch Linux sample option is to put words there.

Hello,

I think you can refer to my EFI folder in Linux Mint 18.2 how to add rEFInd.

I have done something similar to you

Code:
menuentry Linux {
Icon EFI / refind / icons / os_linux.png
Volume 904404F8-B481-440C-A1E3-11A5A954E601
Loader bzImage-3.3.0-rc7
Initrd initrd-3.3.0.img
Options "ro root = UUID = 5f96cafa-e0a7-4057-b18f-fa709db5b837"
Disabled

}

But I think this is wrong because he can not boot rEFInd.

This is my guide code.

Code:
menuentry "LINUX" {
     icon /EFI/BOOT/icons/os_linuxmint.png
     volume "LINXIUMISO"
     initrd /casper/initrd.lz
     loader / casper / vmlinuz
    # options "file = / cdrom / preseed / linuxmint.seed boot = casper iso-scan / filename = $ isofile noeject noprompt splash"
     options "file = / cdrom / preseed / linuxmint.seed iso-scan / filename = boot = casper quiet splash"
}
For SD card, we support up to 128G, you can download Linux Forum Mint to extract to your SD card, and reboot or boot press F7 boot. For SD card boot Linux, you have to use FAT32 format.
Hope these can help you.

Best regards,
Hu

That's how I go rEFInd on my SSD drive.  Would I also need to put it on my removable SD card to make it bootable?

Not the case, if you are added to the SSD and boot, I see your picture situation, you seemingly want to do more systematic guidance? If you are on SSD, I suggest you to add rEFInd to EFI to boot. You could try adding rEFInd to / boot / efi / EFI.

Best regards,

I looked at this page and it said this:

On a UEFI-based system, type efibootmgr -c -l \\EFI\\refind\\refind_x64.efi -L rEFInd to add rEFInd to your EFI's list of available boot loaders, which it stores in NVRAM.
Would this tell rEFInd on my SSD card to boot kernels on my SD card in addition to ones on my SSD card?

Marty
[hr]
I'm getting an error and that file does exist.

Code:
Apollo-N42 tux # efibootmgr -c -l /boot/efi/EFI/refind/refind_x64.efi -L rEFInd
efibootmgr: Could not set variable: No such file or directory
efibootmgr: Could not prepare boot variable: No such file or directory
Apollo-N42 tux # ls -l /boot/efi/EFI/refind/refind_x64.efi
-rwx------ 1 root root 231464 Jan 25 15:52 /boot/efi/EFI/refind/refind_x64.efi
Is this the way to getting the SD card to boot, or should I try another way?

I need some help about how to boot from my removable SD card.  Could u post a screenshot for this? I already have rEFInd installed on my SSD and it boots any OS on it but this is different.

using blkid I have this:

Code:
/dev/mmcblk0p1: LABEL="Elementary OS" UUID="d4ebed1e-3270-42cb-9971-be714f87ef4c" TYPE="ext4" PARTUUID="155724db-01"

Elementary OS is on my microSD first partition and this is in the boot directory:

tux@Apollo-N42 /media/tux/Elementary OS/boot $ ls -lh
total 60M
-rw-r--r-- 1 root root 1.4M Aug  9 07:08 abi-4.10.0-32-generic
-rw-r--r-- 1 root root 201K Aug  9 07:08 config-4.10.0-32-generic
drwxr-xr-x 2 root root 4.0K Jan 27 13:46 efi
drwxr-xr-x 5 root root 4.0K Jan 27 13:53 grub
-rw-r--r-- 1 root root  41M Jan 27 13:55 initrd.img-4.10.0-32-generic
-rw------- 1 root root 3.6M Aug  9 07:08 System.map-4.10.0-32-generic
-rw-r--r-- 1 root root 7.1M Jan 26 23:39 vmlinuz-4.10.0-32-generic
-rw------- 1 root root 7.1M Aug 14 15:36 vmlinuz-4.10.0-32-generic.efi.signed


I tried this but don't see it on reboot:


Code:
menuentry Elementary-OS {
    icon EFI/refind/icons/os_linux.png
    volume 155724db-01
    loader /boot/vmlinuz-4.10.0-32-generic
    initrd /boot/initrd.img-4.10.0-32-generic
    options "ro root=UUID="d4ebed1e-3270-42cb-9971-be714f87ef4c"
    disabled
}
What am I doing wrong?  I'm used to the grub bootloader so maybe I'm doing something basically wrong with rEFInd.  I think the problem is on the volume line.  Arch Linux sample option is to put words there.

Hello,

I think you can refer to my EFI folder in Linux Mint 18.2 how to add rEFInd.

That's how I go rEFInd on my SSD drive.  Would I also need to put it on my removable SD card to make it bootable?

Marty
Not the case, if you are added to the SSD and boot, I see your picture situation, you seemingly want to do more systematic guidance? If you are on SSD, I suggest you to add rEFInd to EFI to boot. You could try adding rEFInd to / boot / efi / EFI.

Best regards,
Hu
I need some help about how to boot from my removable SD card.  Could u post a screenshot for this?  I already have rEFInd installed on my SSD and it boots any OS on it but this is different.

Marty
Hello Marty.

I do not know if the information I provided can help you, but I think you can try it and see the picture.

That's how I was able to install 3 other Linux Ubuntu variants on my SD card, but no matter where u install the bootloader leaves it not able to boot.  I found 2 links from a site that says rEFInd should automatically find the new kernels.  I put a 5 second delay into refind.conf but it doesn't automatically find anything new.  Here are the links:

http://www.rodsbooks.com/refind/configfile.html

Is it possible on this computer to boot from the SD card?

Hello,

For SD card boot is no problem, you can download the system in my forum, extract it to the SD card, and then press [F7] to boot to see if there is no problem.

Since my SD card was previously damaged, I am currently purchasing new tests and I will test your problems one by one.

For the refind.conf you say, first you have to install it in EFI first, and you can check this link: http://www.minisforum.com/showthread.php?tid=6

Check it to modify the refind.conf steps, I believe you will understand more.

Best regards,
Hu
