Lenovo has confirmed that several of its Yoga laptops are refusing to install Linux-based operating systems [bbc.com].
The Chinese firm said the issue had been caused by its switch to a new storage system, which reads and records data faster than normal.
There had been confusion after one of its employees posted that Linux was blocked because of an [imgur.com] "agreement with Microsoft".
However, Lenovo has denied enforcing a deliberate ban.
The restriction affects PCs sold with the "signature edition" of Windows 10.
The term refers to a promise that "junk" software is not pre-installed alongside the OS to avoid slowing down its operation.
The Lenovo rep's response (linked to in the excerpt) seems to have been given before the company PR people got involved.
