Abstract
The present invention is notably directed to a method for allowing an operating system, or OS, to access an encrypted data storage system of a computer (10), wherein: the data storage system (11) comprises: a partition (122); and first encrypted data units (120) that comprise partition table data of said data storage system; and said computer (10) is connectable to an external device (20) comprising: a boot loader (24) for an external OS (112) that is not installed on the computer; and partitioning information (22) capturing an expected location of said partition (122) in the data storage system; and wherein second encrypted data units (220) that comprise reference partition table data for said data storage system are available from said computer (10) or said external device, the method comprising: upon connection (S21) of said external device (20) to the computer, instructing to boot (S23) the computer (10) from said boot loader (24); and during or after booting of the computer: comparing (S25) the first (120) and second encrypted data units (220); and if (S27) the first and second encrypted data units match, allow (S28) the external OS (112) to access, based on the partitioning i…
