How to access bios on a MacBookPro laptop

Sometimes, a hard drive will not boot or run a computer, but its files may

remain intact enough to retrieve once the failed hard drive is removed, by

use of a 'universal drive USB adapter kit' with power supply & cables and

attach it to the bare drive... Then it may be accessed by a healthy computer.

Recovery software such as retail companies have to sell, some may have

a trial version online you could use to see if it says it can recover files, but

the truth would only happen after you bought it, & if it worked. Here's one

that has been around awhile -- though I haven't tried it myself:

So the internal drive has failed and you likely will have to re-install from scratch. 😐

1. There isn’t a BIOS on an Intel Mac. They use EFI.

2. The internal drive appears to be dead. If so, the data on it can only be recovered by a service such as DriveSavers; these can charge hundreds or thousands of dollars.

3. Not normally, but see #2.

1. Data Rescue is a download. It doesn’t itself contain a bootable system, but it can be used to create one on the internal drive if needed. Note that if the Disk Utility doesn’t see the drive, the issue is somewhere in hardware and normal data recovery tools won’t work.

2. See #3 in my post above.

It’s not likely but possible. If it does happen, you wouldn’t need to use data recovery software, as any application would see the content.
