Adding Ubuntu on its own SD card to an ASUS EPC running XP on a first SD card


I have a netbook ASUS EPC S 101
She runs XP SP3 on her main drive, a 16 GB SD card.
She has available another 16 GB SD card, which shows up as a drive under ďMy ComputerĒ.
I would like to install Ubuntu on the spare card, keeping Windows on the main drive card.
Can someone point me to the info to do this?
Thank you.

Download your favorite Ubuntu iso, place it on a USB pen drive using unetbootin, boot from the pen drive, and install to the device corresponding to your second 16 GB SD card. Can you change the boot sequence of the 16GB SD cards via the BIOS? If not, you'll probably need to install grub in the MBR of your XP card. Be sure to back up your XP card first!

Install linux on SD card is a bad idea for a number of reasons.

Most SD cards aren't fast enough to run an OS from (especially swap, which might ruin the card), but also some of the controller chips laptops use for SD cards are extremely slow.

Most BIOS can't boot from these SD slots anyway, so you would have to boot from a hard drive with grub, and then tell the kernel to root from the SD card (it'll be something like /dev/mmcblk0p1

He didn't ask if it would be fast On the other hand, he's already running XP off an SD card. My recommendation would be Puppy Linux (or another small distro) that can run in RAM. I've actually done this, but since my netbook won't boot off the SD card, I had to put it in a USB card reader. Now that was slow!

I believe if you read the title and first thread carefully the OP is running XP from the internal solid state disk and would like to run linux from the SD card. Yes, it is possible to boot from SD card on the Asus netbooks.

I read it carefully. And wondered about running from a 16GB SD card. To the best of my very limited knowledge, the Acer Aspire One ZG5 is the only netbook with two SD slots, abd I've never encountered an Asus EPC, but I'm not familiar with every portable computer on the market.

I do know that one cannot boot directly from an SD card in either of the ZG5's card slots. If I want to boot and run off an SD card, I put the card in a USB card reader - it works, but it's painfully slow.

Thank you very much, RockDoctor, prayag_pjs, and michaelk.
There is more to this than I thought; I did well to ask your advice.
I had thought that mine would be a common idea.

>Download your favorite Ubuntu iso, place it on a USB pen drive using unetbootin, boot from the pen drive, and install to the device corresponding to your second 16 GB SD card.
+
I will make this my first effort.

>Can you change the boot sequence of the 16GB SD cards via the BIOS?
+
Yes.

>Most SD cards aren't fast enough to run an OS from (especially swap, which might ruin the card), but also some of the controller chips laptops use for SD cards are extremely slow.

I donít know if the main drive, which I described as a 16 GB SD card, functions exactly like an SD card that you put into the accessory slot.
I have only used the accessory card for briefly holding a full backup. It showed no slowness, but I wasnít using it to run an operating system from.
The circuitry that controls the main drive may not control the card in the accessory slot.

>didn't ask if it would be fast.
+
No, but the netbook is not slow. I donít use her for gaming or for graphics, and she is the best thing Iíve had since an Apple 520 C.
Loading Ubuntu onto a card in the accessory slot seemed preferable to partitioning the main drive.
Iíll let you all know if it is.
Thank you again.
