ubuntu – grub doesn't see windows 8


Installed ubuntu next to windows 8 (with ubuntu for the first time I'm picking). I split off a piece of 100 gigs from disk C, made 2 partitions of 16 GB for swap and 84 GB for the system. This is what it looks like for me:

/dev/mapper/isw_chdaeggdih_RAID0IMSVolume1      2048   1230847   1228800   600M Windows  
/dev/mapper/isw_chdaeggdih_RAID0IMSVolume2   1230848   1845247    614400   300M EFI Syst
/dev/mapper/isw_chdaeggdih_RAID0IMSVolume3   1845248   2107391    262144   128M Microsof
/dev/mapper/isw_chdaeggdih_RAID0IMSVolume4   2107392 290406399 288299008 137,5G Microsof 
/dev/mapper/isw_chdaeggdih_RAID0IMSVolume5 290406400 323960831  33554432    16G Linux св
/dev/mapper/isw_chdaeggdih_RAID0IMSVolume6 323960832 500121599 176160768    84G Linux fi

Initially, grub was not shown at all, then, using the Grub Customizer program, I configured it to be shown forcibly, but there is no item with Windows in it. What to do, tell me.

PS If you need additional information – write, I will immediately provide it.

UPD: there is not a word about windows in /boot/grub/list.cfg .. How and in what format should a new item with Windows be added there? Maybe there are programs that simplify this action?


With the help of the Boot-Repair program, everything will be fixed quickly.

1) Run Ubuntu from a flash drive

2) In the terminal, write the commands:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

3) Reload…
