Lenovo : erreur 1962 aucun système d'exploitation trouvé

Question

Hello

I need help.. This morning, when I woke up, I got an error message

error 1962 no operating system found

I don't know what to do..

I have an All in One Lenovo.

I checked in the BIOS that the hard drive was in the boot sequence and I tried to do a recovery from F2 but it doesn't find a backup (it's looking in c:/lenovo/ but there's no folder like that) I made a bootable USB stick but with Lenovo the hard drive is locked and it's not possible to do it that way. Sometimes it starts, checks and repairs the hard drive, then it goes back to the errors saying it may take up to an hour and then it restarts and I end up with the same message...

help!

I don't understand why it takes so long after clicking on repair to display troubleshooting, etc...

Good evening,

try this:

Instead of refreshing the PC or formatting, choose Advanced Options, then Command Prompt

Type in the following order:

diskpart (then press enter)
list volume (then press enter. Don't forget the space between list and volume)
You will get a table, look for which letter corresponds to OS. For me, it was C. If it's not C for you, the next line will change ;)
Then type: bcdboot c:windows /L fr-FR (then press enter)
Either it works and you can restore your system by closing the command prompt and clicking on refresh the PC, then restore
If it shows: BFSVC Error: could not open the bcd template store. status = [C000000F]
Proceed as follows:
Type in the following order:
attrib c:\boot\bcd -h -r -s (then press enter)
del c:\boot\bcd (then press enter)
bootrec /rebuildbcd (then press enter)
Normally, it will reinstall something and ask if you want to install it, you will need to type the letter "O" and press enter.
Then close the command prompt.
You will automatically return to the previous page and normally, there will no longer be the "Refresh" box but a new icon saying... "Continue, proceed to Windows 8.1" or Windows 10
Click on it. Your computer will restart, don't forget to keep pressing the escape key while your PC restarts to avoid booting from the USB drive, but to boot into WINDOWS.
The logo of your PC will reappear, your PC will update, restart, and update again.

Quel est le moyen le plus simple d'arriver à l'invite de commande ? J'ai une clé USB de boot pour installer Windows 10 mais c'est toujours long.

pistouri · Answer

have it repaired instead of installing (it is indicated below) the options will appear choose command prompt  -- scalpel

ok so there's nothing simpler than that..

but on the other hand, earlier I ran some commands in DOS and I could see all my folders and directories, whereas now when I do "list volume," none of my internal hard drive partitions are showing up..

pistouri · Answer

you also have F11 for the options of your Lenovo  tap repeatedly at startup hoping it finds the partition  -- scalpel

bre · Answer

Well, the restoration still doesn't work; it tells me that it didn't find any restore points.

If I do the rebuildbcd, it tells me:
number of Windows installations identified: 0

It was able to see my partitions at that time.
What should I do?
