The issue: for several last days:
Mageia´s bootloader got to cyclic reset/reboot. First, the usual menu for booting to Mageia and/or for advanced options (with rescue mode) appear, the it continues with the window with progressbar, but shortly after it cracks and the system make restart, and again and again and again ... Also the hard drive was (foir some money) checked and is OK. The onli option (quick option) remains in 1) formatting the root partition, or 2) the whole disk - all acceptable in this situation, because:
The inserting of DVD with Mageia doesn´t help - the installer doesn´t appear - for me to be able go to expert mode and let make the formatting of partition by choice (first test would be the formatting of root partition, in the case of fail with the second attmpt consisting of whole disk formatting), and fresh new installation.
So, could you provide the command for the command line in rescue mode, that would do:
1) the format of simply root partition - I suppose, I have to "destroy" that in this case unpleasant bootloader repeated activity
2) the format of complete disc
