Hi All - My Aspire V5-571 failed to boot last week giving a repeating beep and then "Operating System not found" in upper left corner. Tried killing power (including pulling battery) and rebooting multiple times with no luck. This is originally a Win 8.1 machine upgraded to Win 10.
I ordered the eRecovery CD set from Acer (based on my SNID, so they should be the right disks) and tried them this morning. The instructions say to start with the System Disk and hit F12 at the splashscreen to bring up the boot menu. I did this (have tried multiple times) and no boot menu ever comes up. This is what I do see and hear:
1. Power on, immediate repeating short (I think) beeps
2. Splashscreen
3. I press F12
4. CD crunches and then whirs
5. Beeping stops
6. After a while wait wheel appears and CD stops making noise (simultaneously)
7. Blue screen
8. Partial DOS box quickly flashes in upper left
9. CD access
10. After a bit Error Message Dialog appears "Fail to get PT Info" with only "OK" as response option
11. I screen-touch "OK"
12. Goes to black screen, then splashscreen and entire sequence repeats.
Hitting F12 or not hitting it makes no difference.
Any suggestions or diagnoses? Bad hard drive? Bad system ware? Thanks for any help
