A Nitro V15 that will not start Windows, boots to a repair screen, or loops through the Acer logo is a problem the community threads mostly attribute to a failed update, damaged system files or a BIOS setting. The first thing to try is time: let Automatic Repair run to the end, which can take ten minutes. If it fails, open Advanced options and try Startup Repair, then Safe mode, where you can uninstall the last update or driver. Acer's own recovery is reached by pressing Alt and F10 as the logo appears, and it can reset the laptop while keeping your files.
An owner whose ANV15-51 would not boot found the BIOS needed its defaults loaded, which you do with F2 to enter the BIOS and F9 to load defaults. If the SSD does not show in the BIOS, the fault is hardware and needs service. Write down exactly what the screen says before you try anything, because a message about no bootable device, a stop code such as inaccessible boot device, and a plain loop to the logo each point at a different cause. Keep the charger connected throughout, since a laptop that runs out of power during a repair can leave things worse.

- The BIOS defaults
- Loading defaults cured one owner's unbootable ANV15-51.
- Recovery key
- A BitLocker prompt is solved from your Microsoft account.
- Stop codes name the cause
- A code such as inaccessible boot device points at the drive or a driver, while a loop with no code usually points at an update.
- Protect your files
- If the SSD is readable from the recovery command prompt or another computer, copy your files before choosing any reset option.
- Acer Care Center
- Once Windows runs again, Acer's utility can update drivers and the BIOS in one place for the exact model.
Stop boundary
When this stops being a self-service repair
