[RESOLU] Passage de Windows 8.1 à 10
Bonjour à tous,
Je souhaiterais faire migrer mon Windows 8.1 vers 10 ou 11 si cela est possible . Le PC est en dual-boot avec Ubuntu Mate 20.04. Il y a-t-il un risque d'écrasement d'Ubuntu ? . Je vous ai fait un Boot-Info
Merci aux futurs intervenants

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sda5,
using the following options: sda2/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Blockers in case of suggested repair: __________________________________________
Please use this software in a live-session (live-CD or live-USB). This will enable this feature.
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.5 LTS CurrentSession entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)Conseils pour les nouveaux demandeurs et pas qu'eux

Re : [RESOLU] Passage de Windows 8.1 à 10
Bonjour Xubu et merci pour le collage.
Bonjour geole,
Merci pour ta réponse.
Je souhaiterais faire une migration sans perte de données de 8.1 vers 10, mais surtout pas le supprimer. Pour 11, ce serait dans un deuxième temps si le PC est compatible effectivement. Mais j'ai peur qu'avec ce processeur, il ne le soit pas.

Re : [RESOLU] Passage de Windows 8.1 à 10
Ton disque est GPT
sda : is-GPT, no-BIOSboot, .et pas MS-DOS. Donc en théorie,il n'y aurait pas les sinistres écrasements de windows7

Tu conclus donc qu'en GPT, il ne risque pas d'avoir un écrasement d'Ubuntu contrairement à si cela était en MS-DOS ?

Re : [RESOLU] Passage de Windows 8.1 à 10
Il y a eu des centaines de cas d'ecrasement mais probablement des millions de mises a niveau Windows 7. Pour windows8, il semble que cela ne soit pas le cas.
De toutes façons, tes données personnelles doivent être régulièrement sauvées car un disque cela tombe en panne toujours au mauvais moment.

Re : [RESOLU] Passage de Windows 8.1 à 10
Bonjour,
Je confirme qu'il n'y aura pas de conséquence sur Ubuntu pour la raison évoquée par geole (table de partitions GPT). Au pire, il y aura peut-être besoin de faire la réparation recommandée de Boot-repair mais ce n'est même pas sûr. Si tu n'en as pas une sous le coude, ce serait utile de faire une LiveUSB Ubuntu Mate 20.04. Avec cette LiveUSB, tu pourras utiliser Boot-repair depuis une session live le cas échéant.

Bonsoir Malbo,
Merci pour ta réponse. Me voilà rassuré par vos interventions toi et geole. Je reviendrai vers vous lorsque cela sera effectué. Si je ne rencontre aucun soucis, je rouvrirai cette discution comme tu me l'avais proposé à l'époque pour créer une partition de partage, si tu es d'accord bien entendu.
Merci et bonne soirée.

Non, ne rouvre pas cette vieille discussion (je te l'avais proposé à l'époque mais je ne savais pas que tu allais remettre ça sur le tapis 2 ans après). Je te suggère au choix : soit tu continues dans la présente discussion pour demander qu'on t'aide à créer une partition de partage, soit tu crées une nouvelle discussion spécialement sur le sujet de la création d'une partition de partage quand tu en seras là .

Bonjour.
Nota avec l'arrivée de NTFS3 de la version ubuntu 22.04 qui dit qu'enfin toute la structure windows est parfaitement bien gérée, je pense qu'on peut envisager de dire que la partition de partage est C: et que les lieux de partage sont sous C:/Users

Re : [RESOLU] Passage de Windows 8.1 à 10
Bonjour,
Dans le boot-info collé par xubu1957 zn #2, on voit
============================== Boot Info Summary ===============================
=> Windows 7/8/10/11/2012 is installed in the MBR of /dev/sda.Apparemment, dans un premier temps (?), windows aurait été installé en mode legacy ?
Je n'ai pas trouvé l'information que sda était partitionné en "MBR" ou en "GPT", il me semble qu'une partition GPT peut avoir un MBR (à confirmer)
A priori, cela me semble incohérent, j'aimerais comprendre, et d'abord savoir si sda est partitionné en MBR ou en GPT

Disks info: ____________________________________________________________________
sda : is-GPT, no-BIOSboot, has---ESP, not-usb, not-mmc, has-os, has-win, 2048 sectors * 512 bytes
parted -lm (filtered): _________________________________________________________
sda:1000GB:scsi:512:4096:gpt:ATA CT1000MX500SSD1Au pire le disque a une table de partition MS-DOS.
Il y a toujours un secteur 0. Si table de partition GPT ce secteur est souvent appelé MBR-PROTECTOR.
S'il a été mal initialisé, il peut rester un résidu.
Si le boot est legacy, ce résidu est un vrai MBR qui pointe sur une partition de boot avec drapeau Bios-boot.
Ajout En mettant sous ce niveau, Le logiciel graphique de ubuntu ne voit pas la structure C:/Wiindows
Donc le risque de supprimer accidentellement le logiciel windows est inexistant.
Avantage. On n'a pas deux partitions NTFS à équilibrer en terme de place disque et pas de déplacement des données du C: à faire.

Re : [RESOLU] Passage de Windows 8.1 à 10
Je me permet d'intervenir pour 2 points :
1)
malbo a écrit :

En réalité la vraie question à se poser c'est surtout de savoir où est GRUB avant action car suivant les cas soit il faudra le réinstaller car windows l'aura écrasé pendant sa migration soit il faudra juste rechanger la priorité de boot dans le bios...
2)
Sinon à part ça quoi qu'il en soit contrairement à ce que propose geole je déconseille un stockage de données perso dans une partition système et encore moins si ce n'est pas celui qui est couramment utilisé... Principe de sécurité de base obligé...

Re : [RESOLU] Passage de Windows 8.1 à 10
@FrancisFDZ : bien vu.
Du coup, en y regardant de plus près, je me rends compte que sda est un CT1000MX500SSD1, c'est à dire un SSD interne Crucial MX500 de 1 To, alors que le disque dur de l'ancienne discussion (voir ici en 2021) était un TOSHIBA MQ01ABD1 (disque dur interne de 1 To). Comme le partitionnement est identique, je ne m'étais pas rendu compte de ce remplacement.

Re : [RESOLU] Passage de Windows 8.1 à 10
Bonjour à tous,
Oui effectivement depuis l'installation d'Ubuntu sue le PC, j'ai remplacé le DD par un SSD de même taille et j'en avais profité pour augmenter la RAM. Ce fut fastidieux comme vos pourrez le constater ici. Toujours pas d'opposition pour la MaJ Windows ?
Pour la partition de partage, j'ouvrirais une nouvelle discutions.
malbo a écrit :

À l'époque, je n'en voyais pas l'utilité, comme Windows ramais énormément. Mais depuis les changements cité plus haut, il fonctionne normalement maintenant.
Merci à vous

Re : [RESOLU] Passage de Windows 8.1 à 10
Bonjour,
Finalement je viens seulement d'effectuer la migration. Celle-ci c'est très bien déroulé. Aucun soucis rencontré, même pas pour le GRUB. Il fallait juste être attentif pour les redémarrage, vue que je n'avais modifié l'ordre.
Pour la partition de partage , on s'y attelera plus tard.
Merci à vous tous
