M-NotePC3 初期化

debian、dual boot、win10

１．＠win10 更新とセキュアリティ→PC初期化　30min

2．Windows インストール: 30min

3. Win10が立ち上がってさらに更新プログラム：several min

4. Desktopに”削除されたアプリ（html)”

5．Windows side;　user section; as was.

6. debian：bios で選択すると立ち上がる。内容はOKのようだ。

7. Bootable usb　からの起動：依然として不可能；どうやっても結局win10 に入る。．

mount usb to /media

未分類
  1. Better; su root
  2. .ls /dev; without usbstick
  3. .ls /dev; with usbstick connected
  4. compare 2. and 3.
  5. select the extra one possibly having number at the end; e.g. sdb1
  6. mount -t vfat /dev/sdb1 /media ; you may not need option -t vfat; you may not need to be root.
  7. you will see usb stick on filemanager
  8. you ca unmount it on filemanager.

  1. “japantourguide.net” has been installed in the root directory.
  2. Move everything except the directories for the sub-domains to the new japantourguide directory.
  3. Without modifying the “.htaccess” which is suggested by the WP.org, only change the directory in the LoLipop users setting.
