Haven't tried this with an SD card. What might work would be to have both the hard drive in the main hard drive slot and the SD card in it's slot (or connected via an external drive enclosure or cable). At the BIOS splash screen press F12 to get the BIOS boot menu, then choose the SD card to boot. That said, I am not sure that an SD card would ever be bootable - although that likely would depend upon how new your machine is.
My experience in using the product recovery disk set is that you have a bootable CD (or DVD) that you boot from, followed by data CD's or DVD. However see the following:
Using Recovery Media
You can use recovery media to restore your system drive or hard disk drive to the original factory contents depending on your individual needs.
Attention: When you restore the factory contents using recovery media, all files currently on the system drive or hard disk drive will be deleted and replaced by the original factory contents.
To use your recovery media, do the following:
Depending on the type of your recovery media, connect your boot media (memory key or USB hard disk drive) to your system, or insert the boot disc into your CD or DVD drive.
Restart your computer.
Press F12. The Boot Menu window opens.
Depending on the type of your recovery media, select the proper boot device and press Enter. After a short delay, the Product Recovery program opens.
Depending on your needs, select your preferred language in the drop-down list box. Click Next.
Select I agree to these terms and conditions check box and click Next.
Select the recovery media in the drop-down list box.
Note: If your recovery media do not display in the drop-down list box, click Refresh to refresh the recovery media list.
Select Restore Windows partition (C partition) only. or Restore to factory default state (all data on the system hard disk drive will be lost). depending on your needs. Click Next.
Follow the instructions on the screen.
Note: After restoring your hard disk drive to the original factory contents, you might have to reinstall some software or device drivers.
I believe you should be able to create the "Boot Media" more than once, but probably not the "Data Media". Could be wrong though.
The Create Recovery Media program enables you to create recovery media to restore the contents of the system drive or hard disk drive to the same state as when the computer was originally shipped from the factory. You can create the recovery media on a memory key, a USB hard disk drive, or a set of discs if your computer is equipped with a recordable CD or DVD drive.
Recovery media are useful if you transfer the computer to another area, sell the computer, recycle the computer, or as a last resort put the computer in an operational state after all other methods of recovery have failed. As a precautionary measure, it is important to create recovery media as soon as possible.
Note: The recovery operations you can perform using recovery media vary depending on the system from which they are created. Your Microsoft(R) Windows(R) license permits you to create only one data medium, so it is important that you store the medium in a safe place after you make it.
To create recovery media, do the following:
Click Start > All Programs > Lenovo ThinkVantage Tools > Factory Recovery Disks.
Select The recovery media you are going to create can only be used on this system. Do you want to proceed? in the Recovery Media section.
Select the Boot Media check box or Data Media check box depending on your needs. Click OK.
Note: It is recommend to create both boot media and data media if you are creating the recovery media for the first time.
Select the medium on which you are going to create the recovery media in the drop-down list box.
Click OK and follow the instructions on the screen.
