Reading internal hard drive which had Ubuntu installed on it, to be able to read on Windows 10?

Solution 1:

Note: Windows can read Linux ext2/3/4 partitions with the addition of a Windows driver... but DON'T do it, 'cause it'll surely corrupt the Linux file system.

Here's the safe way to do it...

1. Connect the old Ubuntu drive via a USB->SATA cable.

Note: Some USB->SATA converters can't read/write to previously formatted drives without a reformat (thereby wiping the drive). This is due to the internal chip used in some converters. If this is your case, you'll have to connect the drive to a physical SATA port on some other Ubuntu computer to be able to access your files.

2. Boot your computer to a Ubuntu Live Desktop USB flash key, or DVD.

3. You should be able to read/copy files from the old Ubuntu drive to your Windows C: partition, or to another USB flash key, or external drive that uses NTFS or FAT.
