After installation of Ubuntu 14.04 64 bit on a notebook HP-15-r248nf with Windows 8 upgraded to 10 installed which happened smoothly besides a problem with a dropping Wifi connection with a Realtek Wifi driver (solved using echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf ), the PC still booted under Windows. Ubuntu through grub became only available when using the ESC key during the boot phase. boot-repair did not help, it actually installed quite a number of options in grub, but grub was still not directly accessible. In fact it was simply required to change the boot order from the default. At the boot step after switching on the PC type Esc, then F10 to enter the BIOS setup. Go to the tab “System configuration”, down to “Boot options”. Press Enter. Disable “Secure boot” Go down to UEFI Boot order. I put using F5/F6 the OS Boot manager on top (probably not required). Select “OS boot manager” with Enter. Using F5/F6 move ubuntu to the top above Windows Boot Manager. Leave the Bios setup with F10 Save/exit and confirm the changes you made. Now you will be directed to grub where you chose the option Ubuntu marked with a star on top which will boot automatically after a short delay.

This is what I did:
I booted into my Ubuntu installation using the trick of the F9 key in the start up to be able to choose the boot loader.
Once in Ubuntu, I opened a terminal.
Using the command below, I checked where Windows boot loader was located:
$ sudo efibootmgr -v
In my case, the original boot loader was in here: /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi . Please note that in your computer it might be in a different place. If so, you will need to adjust the commands below.
As per Rod's recommendation in his answer (the one about how to repair the boot loader manually), I made a backup of that file by moving it one level down:
$ sudo cp /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi /boot/efi/EFI/Microsoft/bootmgfw.efi
Finally, I copied GRUB2's boot loader in that place, "tricking" the system into loading the boot loader I wanted instead of Windows' original boot loader.
$ sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
So finally I had my dual boot working with GRUB2. In case Windows overwrites the boot loader again after an update (as it did with me), I already know the steps to get grub back to its place.
Hope this helps someone. Please let me know if there are any issues with my solution.

Tänään on muuttunut vain nauhoitus.zip tiedoston sisältö jossa on kaksi eri Launchy xml-tiedostoa ja uutuutena nauhoita_matala joka nauhoittaa silloin kun pyydetään alempaa tarkkuutta.
En saanut noita paketteja asennettua Xubuntu 10.04:än. Pika-asennus ilmeisesti asensi vain uuden Rtmpdump'in, joka sitten herjasi GLIBC 2.17 puutteesta. Semmoisen paketin löysin, mutta ei asennu.
Ratkaisuna Rtmpdumpin poisto ja vanhan yle-dl_2.1.0-1_i386.deb paketin asennus. Yle-dl skripti varmuuskopiosta, eli nimen muutos yle-dl'ksi ja ajo-oikeuden anto.

Tuosta linkistä se on hirmu helppo asentaa.
eject /dev/sr1[code] toinen läppärini (Toshiba L450D-144) löytää tikun ja alkaa toimia, mutta toinen läppäri (HP 530) jumiutuu niin että se pitää käynnistää virtakytkimestä.
Luulisin että ratkaisu voisi löytyä Nokian omasta yhteysohjelmasta, mutta sitä ei löydy tikusta.

Hi,
I have a Nokia CS-17 stick, which I got working using the following config file /etc/usb_modeswitch.d/0421:0622:
Code:
########################################################
# Nokia CS-17
DefaultVendor= 0x0421
DefaultProduct=0x0622
TargetVendor= 0x0421
TargetProduct= 0x0623
CheckSuccess=20
MessageContent="5553424312345678000000000000061b000000020000000000000000000000"
and by adding an udev rule:
Code:
# Nokia CS-17
ATTRS{idVendor}=="0421", ATTRS{idProduct}=="0622", RUN+="usb_modeswitch '%b/%k'"
to the /lib/udev/rules.d/40-usb_modeswitch.rules file.
I didn't use any USB sniffer but just tried the config file modified from the CS-15 config and it worked so I assume that the MessageContent line above is correct.

Miten tehdään tuo config file?
Korjataanko udev.rule komennolla [code] copy con: /lib/udev/rules.d/40-usb_modeswitch.rules file ja kopioimalla yllä oleva pätkä sinne?
