'm getting an Advent 4211 to use as a compact laptop for general use. The absence of a CD drive is potentially limiting but not insurmountable for my needs. I've seen reference to using the integral SD to create a backup of the Restoration Partition, which I believe Advent recommend, and I've seen the option to boot from SD on the Laptop. I believe the only option offered on booting with this Laptop apart from the HD is the SD. On a PC I rarely ever use a bootable CD and instead install Acronis True Image and use Startup Recovery Manager - F11. I don't want to partition the HD. In the event of warranty issues I want to keep the set up as close to original as possible. I've read the excellent guide to creating a bootable USB drive containing Rescue Media. http://www.wilderssecurity.com/suppo...ble_usb_hd.pdf On the Advent I anticipated installing TI to create images and relying on booting into TI for restoration. I was hoping therefore to create an Acronis bootable SD and on booting from the SD card, TI would run and allow selection of an image from an external USB HD or USB Pen Drive. Reading the guide I have a strong suspicion it's not that simple. If what I am hoping to do is not possible is it likely that I can follow the guide and substitute the SD card for the USB flash drive. In that event will the MBR on the integral HD be overwritten. The laptop will come with XP home and I have Acronis TI 8 and 11.
