Need a clean install of your Acer Iconia W500 series tablet but didn’t opt for the external cd/dvd drive?
Normally you can restore via a hidden partition, but more often than not that has been removed or failed.
After some serious back and forth trying a number of things to copy the Iconia W500 system restore cd’s to a USB stick i found this is the easiest way to go about it.
A couple of the issues i ran into were:
Stuck at 99% – asking for cd2
After copying the CD contents to my USB and booting from it i was getting stuck at 99% when then it would ask for cd 2, nothing i could do would make it recognize the second USB stick.
BOOTMGR is missing
After i formatted and attempted a fresh copy of both cd’s to the 1 USB drive, i found i couldn’t boot from the USB stick – this is because the format i completed made the drive non bootable
After some trial and error i have the complete process i followed to restore my Acer Iconia W500 series tablet from USB stick rather than CD/DVD.
You will need a USB stick that can fit the entire contents of the 2 restore cd’s
Part 1 – Create bootable drive formatted with fat32
- Windows key + “R” opens “Run”
- Type diskpart and press Enter
- Issue the following commands
- list disk Enter
- select disk # Enter (look at the list of disks to decide which one is your thumb drive)
- clean Enter
- create partition primary Enter
- select partition 1 Enter
- active Enter
- format fs=fat32 quick Enter (this step will take a few minutes)
- assign Enter
- exit Enter
Part 2 – Copy all recovery disks to the USB thumb drive
Copy the contents of your recovery cd/dvd’s to the USB disk drive, start from the first and work your way through, overwrite if prompted.
Part 3 – Edit Restore.dat and RCD.DAT
In order for it to work from the 1 USB stick we need to edit 2 files as follows, they are in the root directory. Edit with notepad or similar text editing software
Find the line that says “PCS = 2” and change it to “PCS = 1” and save.
Find the line that says “DiscNumber=2” and change it to “DiscNumber=1”
Part 3 – Recovery
- With the machine powered off, insert the recovery USB you created into the tablet dock USB port.
- Power on
- At the Acer logo screen, press F12.
- Select the USB drive at the following boot menu.
You should now be able to step through the restore process via the USB stick method.
