On my Travelmate 7750G-6494, I replaced the original 500GB HDD with a new Crucial MX500 SSD, then used the Acer disk set (P/N: RD.NGAA7.022) that Acer sent me back in 2012 in case I would ever need it. I selected the third restore option which says: "Restore your computer to factory default status. All data in the hidden partition and on the system partition will be restored. Before restoring, please delete any data on the hard disk." There was no data to delete, since it was a new SSD that I received this weekend. I was not prompted to enter the Product Key on the bottom of the computer, so I assumed it got the product key off the motherboard.
Per the instructions, the first disc used was the System disc. When it finished, the disc drawer opened and I was prompted to insert Recovery Disc 1 of 3. After Recovery Disc 1 finished, I was prompted to insert Recovery Disc 2 of 3. After Recovery Disc 3 of 3 finished, it did what the instruction said it would do: "the system will reboot." Windows 7 started but got the same error code 0x241 as in:

"Restore failed - Error code = 0x241 WIMApplyImage cannot apply image: Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be [top of next line visible but unreadable since there is no scroll bar]." And so on.
This time, it's clear that the recent software change was running the Acer recovery disk set on a new SSD that had no files on it. Is this a bug in Acer recovery disk set P/N: RD.NGAA7.022? If so, I'll install Windows 10 on the Travelmate instead. If it's a hardware problem, what hardware problem would cause that error message after the Acer disk set loads all the files onto a new SSD?
