Hey. I have an Acer Aspire 5 A515-51G laptop and the error "no bootable device". I tried to change UEFI to Legacy and change the boot order but it didn't help. I think I need to manually repair the boot partition. And here's my question - how to do it, because this laptop has unusual names of these partitions and I don't know which one it is responsible for.
I would like to avoid installing the system from scratch. I tried to do it by bootrec /fixboot but it shows error "acces denied" . Please help ;_;.

Laptop BIOS must be set to UEFI mode. Does the HDD or SSD show up in the BIOS INFORMATION tab? Also make sure the D2D and F12 boot options are turned on in the BIOS MAIN tab. Jack E/NJ

This does not seem to be a factory installed Win10 since it was installed on an MBR-partitioned, not GPT-partitioned, HDD. It won't boot in UEFI mode, only Legacy BIOS. If it won't boot from Legacy, you must convert HDD to GPT partition, and re-install Win10 from the USB drive in UEFI mode. Jack E/NJ

I looked through the hirens cd and all the files are there, maybe I could fix it without reinstalling and changing to gpt?

If you want to try to keep the HDD MBR partitioned with the Windows system on it now, volume 1 must be re-labelled the C letter. Volume 0 should NOT be labelled C. In fact, you should remove any assigned letters from Volume 0 and volume 2 as they are not necessary.Jack E/NJ

Ok. So I will fix this labels and then... I don't know. I think I must fix this with bootrec or something. What you think about that?0

Fix the labels first. Then make sure the BIOS is in legacy mode. If it still won't boot, then yes we will try to repair the ESP system reserved FAT32 partition using the USB Win installation drive's X : \ windows\system32\>_ command prompt. Jack E/NJ

I have repaired these labels but still display the same error. In UEFI mode "no bootable device" and in Legacy mode "an operating system wasn't found"0

It must be in LEGACY mode before we proceed any further!!!!!! Jack E/NJ

It is in Legacy mode. ;<. The previous photo too.0

OK. Boot from the USB installation drive so you can get to the X : \windows\system32\>_ command prompt. Then enter the following 3 commands in the order presented. If you get any error messages after each command. STOP and report back. Jack E/NJbootrec /rebuildbdcbootrec /fixmbrbootrec /fixboot

OK. Boot again from the USB installation stick. Now try automatic repair from the troubleshooting advanced option section. Jack E/NJ
