Zaten manjaro'yu kurunca bunu grub kendi ayarlayacak bunun için senin birşey yapmana gerek yok. Sadece ata'nın vermiş olduğu linkteki yolları izle. Bir de benden sana bir tavsiye. Eğer windows 10'dan linux klasörlerine ulaşmak istiyorsan ext4 değil, ntfs kullanmanı öneririm. Misal linux'ta bir dosya indirirsin, windows'tan çekmek istersin, windows ext4'ü okuyamaz ve o bölümü göremez. FAT32 önermememin sebebi performansının ntfs'den düşük olması. Ayrıca eğer bağlama noktalarını (Yeterli bilgin varsa, /, home, boot gibi ayarları) ayarlarsan sonraki kurulumlarında verileri yedeklemen gerekmez, ayrıca bunları bilmenin bazı avantajları da var. Çok önemli değil bir detay değil, eğer bilmiyorsan bildiğini yap.

maalasef ata'nin vermis oldugu linkdeki anlatimi okumadan kednime gore bir kurulum yaptim. su an icin Manjaroda bir sorun yok, sorun o ki, Windows 10 a ulasamiyorum. gruba Windowsu nasil eklemem lazim?

Windowsun kurulu oldugu bolum  /dev/sda2 dir, Manjaro /dev/sda3 de kurulu

sudo update-grub

denermisin ?

os-prober paketi yüklü mü ? İlk sorulan paketler arasındadır bu tür durumlarda. os-prober yüklü değilse yükleyip tekrar

sudo update-grub

denermisin ?

http://archtr.org/forum/viewtopic.php?t=693#p6359
yukarıda lınkde anlatılanı dene ayrıca oradaki aşağıdaki kod ile wın dahil sıstemdeki tümümünü gruba ekler

pacman -S grub os-prober

manjaro dev/sda3 olduğunu söylemişsin şöyle yapalım  live yanı manyaro kurulum flash yada dvd ile başlatıp
masa üstüne gelince  terminali açıp şunu yap root olarak

mount /dev/sda3 /mnt

pacman -S grub os-prober

grub-install /dev/sda
grub-install --recheck /dev/sda
update-grub
