I had windows 7 and ubuntu 12.4 LTS installed for months.. have important data in both sections especially under root account of ubuntu... and D and G drives in windows partition.. not much in the host partition of windows.
Recently found a .Trash hidden folder under G drive. Read that it is not a virus.. came from saving files from ubuntu in newvolumeG.
Was going smoothly except for a few unity issues. Which i was slowly learning to get rid of.. to get my convenient desktop back. Had swap partitions with missing UUID.. dev/mapper/cryptswap not found error was there.. .bashrc file showed a filename instead of a uuid of the sda6 or 8. There were two swap partitions.. one with 2 gb another with 5 gb. None were used after the error started to show up as i guess after i checked disk-utility.
A few days ago i unpluged LAN cable. Was doing some offlne reading of offline saved web pages on unity issues. Net was not needed. And i sometimes do. Within 24 hrs a strange ticking sound started like when a cd gets stuck. I got afraid and closed the lid. Did not open the lappy for two days. Now when i attempt to start in place of grub being loaded with list of partitions to boot into it gives me this on a blank screen. atheros PCIE ETHERNET CONTROLLER CLIENT MAC: 6 SEGMENT HEX GUID ... some more hex... PXE-E53 : NO BOOT FILENAME RECEIVED PXE-M0F: EXITING INTEL PXE ROM
That strange sound is still coming possibly from HDD. My lappy is a Toshiba satellite c665 pc Cd drive not working. USB working. Need to save and access all data under root and windows D and G drive.
